Talking with teens about drugs and alcohol may not be the easiest thing. But research shows kids whose parents do, are 50 percent less likely to abuse those substances. One family is going beyond the talk, and developing a plan we can all learn from.Snack time at the Wardell house is more than a time to eat. It's also a chance for Karla Wardell to check in with her kids. And while these topics may be light ones, conversations on heavier topics don't look much different.  Wardell says she started talking with her teenage children, Brandon and Elissa, about drugs and alcohol when they were young. She says she's honest with them about the reality of drugs and alcohol, and pushes them to think about how they might react if around them. And if there's a situation her kids can't get themselves out of, the Wardell's have developed a plan for that.  "We have a little code word they can text or a call," Karla Wardell says. "And if they text and they write something like what time do you want me home but if home is all capitalized that is their SOS to me like I want to come home."  Elissa Wardell has had to send her mom a text like that, and even uses a way to delete it to be even more discreet.  "Your friends won't be able to see that you have said I want to go home," Elissa Wardell says. "They will just think that your parents are being mean and you can go home."  Steve Martinez works with Speak Now, a campaign that encourages parents to have conversations with young ones about the dangers of substance use.  "If a parent feels that it is wrong for example to binge drink or use substances, that teens are three times less likely to use," Martinez says.  Martinez says conversations can happen anywhere, and can start when a child is as young as nine. He says approach matters, and scare tactics don't work.  What does work? Building trust. One conversation at a time."The bond that parents have with their kids is it's really special," Karla Wardell says. "And we need to recognize that and our kids will listen to us if we have the courage to talk with them." 2126

Tall people are at a greater risk of cancer because they have more cells in their body, new research has suggested.A person's risk of developing cancer increases by 10 percent for every 10 centimeters (4 inches) they are over the average height, the study said, because they have more cells which could mutate and lead to cancer.Average height was defined in the study as 162cm (5 feet, 4 inches) for women and 175cm (5 feet, 9 inches) for men.The findings match with previous research, which has also connected height to an increased risk of developing a range of health problems including blood clots, heart problems and diabetes.Leonard Nunney, a professor of biology at the University of California Riverside, analyzed previous sets of data on people who had contracted cancer -- each of which included more than 10,000 cases for both men and women -- and compared the figures with anticipated rates based on their height.He tested the hypothesis that this was due to the number of cells against alternatives, such as possible hormonal differences in taller people, which could lead to an increased rate of cell division.A link was found between a person's total cell number and their likelihood of contracting cancer in 18 of the 23 cancers tested for, the study says.The research also found that the increase in risk is greater for women, with taller women 12 percent more likely to contract cancer and taller men 9 percent more likely to do so. Those findings matched with Nunney's predicted rates, using his models, of 13 percent for women and 11 percent for men.Colon and kidney cancer and lymphoma were among the types of cancer for which the correlation was strongest."We've known that there is a link between cancer risk and height for quite a long time -- the taller someone is, the higher the cancer risk," Georgina Hill from Cancer Research UK told CNN."What we haven't been sure of is why -- whether this is simply because a taller person has more cells in their body, or whether there's an indirect link, such as something to do with nutrition and childhood," added Hill, who was not involved in the study.She said the study provides good evidence of the "direct effect" theory that the total number of cells does indeed cause the link."The methodology is good - they took data from large studies, which is important, and they looked at lots of different categories of cancer."But she noted that the increase in risk of developing cancer is small compared to the effects that lifestyle changes can have."It was only a slightly higher risk and that there are more important actions that people can take to make positive changes, [such as] stopping smoking and maintaining a healthy weight," she said.Two of the types of cancer tested for, thyroid cancer and melanoma, were found to be more susceptible to an increase in risk than expected, and Nunney suggested in the study that other factors could be at play in those cases, such as geography."There are no obvious reasons for these exceptions, although the author speculates that cell turnover rates may come into play for melanoma," Dorothy C. Bennett, director of the Molecular and Clinical Sciences Research Institute in London told CNN. Bennett, who was not involved in the study, explained that pigment cells, the source of melanoma, divide and are replaced a little faster in taller people."But I cannot at present think of any reason why this [faster division] should be so, but nor any other clear reason for the higher correlation with height," Bennett said. 3548

Students around the United States are walking out of class to demand tougher gun laws in response to last week's deadly shooting in Parkland, Florida, but some schools are threatening them with harsh punishments.The Needville Independent School District in Texas issued a warning Tuesday that anyone who participated in a walkout or other political protest would be suspended for three days."Life is all about choices and every choice has a consequence whether it be positive or negative. We will discipline no matter if it is one, fifty, or five hundred students involved. All will be suspended for 3 days and parent notes will not alleviate the discipline," Superintendent Curtis Rhodes said in a statement posted on the Needville High School Facebook page.Rhodes said the Houston-area district would not tolerate any protests or demonstrations during school hours."A school is a place to learn and grow educationally, emotionally and morally. A disruption of the school will not be tolerated," he said.The letter was posted on the same day that a 14-year-old was arrested at Needville Junior High School and charged with making a terroristic threat.Survivors from Marjory Stoneman Douglas High School in Parkland have been active in the week since the shooting -- holding rallies, being interviewed by national media and organizing a bus trip to the Florida State Capitol to meet with lawmakers.Students at other schools in Florida and across the United States have held rallies to show support.A school district in Waukesha, Wisconsin, sent a letter to parents telling them that the school district is not involved in a walkout that is scheduled for March 14 and that teachers and students would not be excused if they participate."Participation in a walkout is disruptive and against school regulations, and will subject students to disciplinary measures," Superintendent Todd Gray said in the letter.In a follow-up statement on Wednesday, Gray said the the original letter was designed to let parents know that the walkout next month was planned by an outside group with no connection to the school."At no time have we said students cannot make a statement peacefully while staying in school," Gray said, adding that he had not gotten requests to participate from any students or student groups."We acknowledge that individuals have a right to demonstrate to support a cause. Therefore, if parents wish to excuse their children from school to attend such an event or demonstration, that is their right," he said.Are you participating in student walkouts?

Student loan debt has surpassed trillion. It's expensive to go to school, and loans help many afford higher-education but not all that money may be going toward tuition and books.A survey found that one in five college students are using some of their leftover loan money to dip their toes into virtual currencies like Bitcoin.The mere mention of cryptocurrency is enough to make Loyola University Maryland Assistant Accounting Professor JP Krahel cringe.“Oh, oh boy,” said Krahel with the Sellinger School of Business.Even worse, students are buying into it and they're using student loan money to do so.The allowance meant for living expenses is instead being invested into Bitcoin and Ethereum. The Student Loan Report found that's how 21 percent of current college students are using their excess financial aid money.“Given the unregulated market of cryptocurrency, given what we've already seen, proven volatility, and given the fact that student loan debt is something you can't get rid of in bankruptcy, I personally, without getting too hyperbolic here, I would not do that,” Krahel said.A warning from someone who knows money, but even his wisdom is not enough to convince some of his own students.“They'll say, ‘Oh, did you see what bitcoin did yesterday, I made x dollars,’ I'm like, children, come on. Your interest rates and student loans that's what you should be worried about. If you have free money, send it back to Sallie Mae, you know, pay that debt off early because that stuff starts snowballing and paying off debt is a guaranteed return on investment,” said Krahel.And yet it's hard to shake the promise of investing in a market that's produced millionaires from relatively low investments just several years ago.“I don't want to knock cryptocurrencies, they do have a value, but people are getting into it because of that volatility, because you could have a thousand today and ,000 tomorrow,” said Krahel. “So, if you're willing to only see the upside, cryptocurrencies are great but that's not the way life works.”Bitcoin's value has sunk ,000 in the last month and plummeted from its peak in December at nearly ,000.However, with every slump there's also the possibility of a rally. These students could prove their professor wrong or learn a real-life lesson about loss and spending wisely.Krahel said you should be borrowing the least amount of money possible so you have less to pay off in the future.Students are graduating with an average of ,000 in student loan debt. 2541
