Are other drinks besides water still hydrating?

I frequently hear that beverages with caffeine or alcohol are not good for replenishing fluids and preventing dehydration. But in reality aren't they just a bit less effective at hydrating your body than other beverages? In other words, if you were stuck in the desert with nothing to drink but beer, coffee and cola, would you actually be worse off and die of thirst sooner if you drank these beverages versus not drinking anything at all?


What are sexual positions people with disabilities can try?

I have been dating this guy for ten years. We both have physical disabilities and therefore have very limited movement. However, we have complete sensation. We really want to have sex but are having difficulty with positioning. Since I have a little more movement than him, I am going to be the one who does most of it. We have had two very unsuccessful attempts and are getting very discouraged. We really love another, but are losing hope. Any ideas?


Why do my calves hurt when I walk?

I am a woman who has a family, full-time job, and a very busy life, generally.

Three years ago, I joined a local health club because I was not getting enough exercise. Since then, I have tried to work out three times a week. Every time I exercise on the treadmill, even though I am not running but only walking fast, I experience leg pain in the back of my calves. I have tried stretching to warm up but nothing seems to help. Do you have any suggestions? The pain in my calves is preventing me from increasing my speed and improving my conditioning. I would appreciate any suggestions you might have.


Is my hair loss due to my vegetarian diet?

I have been a vegetarian for two years. Since last year, I have been losing quite a bit of hair. I have no pattern of male baldness in either side of my family. I do take multi-vitamins everyday. My diet is fairly nutritious. Could there be any correlation between my vegetarianism and the hair loss? Some books point to folic acid deficiency so I have made an effort to buy vitamins with 100%-200% RDA recommended folic acid. Do you have any ideas on what might be causing this?


How do I learn to not judge interracial relationships?

I find that I get a feeling that I do not know how to explain; it is sort of a sad, discouraged feeling, when I see a black man with a white woman. I am a black female adolescent (20 y/o). I am not a racist. Also, I know of many people both black and white who are not racists but feel the same way. I am not angry at interracial couples when I see them together or anything of that sort. How can I be at ease when I see them, besides that it is not my business? I want to know what possible underlying causes can make people feel this way. How do I unlearn this habit?


How long should I wait to use Viagra after using poppers?

I know that it is extremely dangerous to mix viagra (or other ED drugs) and poppers (amyl nitrate), and that one should wait for 24 hours after using viagra (to let it get out of your system) before using poppers. My question is what is the waiting period after using poppers before it is safe to use viagra? In other words, how long before the physiological effects of poppers wear off?
