Should I be concerned about BPA from hard plastic water bottles?

I use Nalgene bottles for about 75 percent of the water I drink each day. Therefore, I was startled to find out that there is some possibility that these bottles leach chemicals into the water. I've found conflicting opinions about the veracity of these claims on the Internet. What's the truth? Should I dump my Nalgene for glass? You have an earlier post about bottled water, but it doesn't seem to address this issue specifically, and you recommend purchasing reusable bottles like the ones that might be poisoning me. The bottles I use have #7 on the bottom in the recycle symbol.


At what age can I get the HPV vaccine?

I am 28 years old, and became sexually active two years ago. My husband is the only man I've ever had sex with, and I am his only sexual partner as well. Where does the gene or whatever it is that the HPV vaccine helps guard against come from? Because I'm too old to get the vaccine, are my chances of getting cervical cancer from this particular gene increased then? Thank you for your help.


What are my chances of getting cancer if I have high-risk HPV?

I just found out I tested positive for high-risk HPV. My pap smears have been normal for years. I'm 45 years old and have had lots of basal cell skin cancer. I'm scared to death of getting cancers that are caused by HPV. I'm so stressed. What are the odds that I will actually get cancer, now that I am supposedly high-risk? It appears there it nothing I can do at all to prevent this from happening other than keeping up with my visits and pap smears and hoping I beat the odds. I just wonder at how much risk am I when they say I am HIGH-RISK???


Does sweating release toxins?

After practicing yoga in normal temperatures for years, I recently attended a heated yoga class (heated quite hot: 95 to 100 degrees!). The experience left me dizzy, nauseous, and completely enervated. Afterwards, I expressed my concern to the teacher, asking why the studio needed to be so hot. She "explained" that by sweating, supposedly the body releases "toxins" and that my nausea and dizziness must indicate that I need to "detox." Personally, I think I was suffering from heat exhaustion. I've heard this silly explanation more than once, as many people seem to believe toxins are released through sweat. But is that true??? And — next question — doesn't exerting oneself in extremely hot temperatures seem like a recipe for dehydration? Are their any benefits that make it worthwhile, or is all this heated yoga just nonsense?
