How can I measure my heart rate and exercise intensity?

1) I work out on my treadmill 20 to 30 minutes a day, usually one to two miles. My husband says that there is a minimum and maximum heart rate. Is there a formula that I can use to calculate this information? Please advise.

2) Is there an equation that would relate the relationship between exercise and heart rate. I understand the maximum and minimum heart rate equations for exercising. I would like to know if someone who is at their max. heart rate would be able to predict their heart rate if they increased their intensity. I am looking for something relating work intensity to heart rate.


How can I tell my religious parents that I'm a lesbian without them disowning me?

I have a question that I am very afraid to ask anyone else. I am a 21-year-old college student who has been in a three year lesbian relationship with my college roommate. We are both deeply in love with each other and when it came time to tell her parents about our relationship, they were very supportive of our decision. My parents, on the other hand, are a different story. I was brought up in a very strict Roman Catholic family, where homosexuality is very much frowned upon. How can I tell my parents that I am a lesbian and make them understand without disowning me?


Why do I get a yeast infection every time I have my period?

I am a 26-year-old female and have started getting a yeast infection every month without fail at the end of my period. This started about a year ago and I've cut back on eating bread, I don't eat much sugar and I rarely drink beer. I read online that someone recommended using a douche just before and after starting my period. Is this a reasonable thing to try? I've always been very opposed to douching but I'm sick of the itching and don't want to have to take medication or use cream every month. Any suggestions?


Is it safe to rub my eyes?

I find it relaxing, along with rubbing my face, to rub my eyeballs (with my eyelids closed, of course). It feels good to massage the muscles and squeeze out the air that builds up back there. Is this safe? Do I risk deforming my eyeballs and changing my vision?


Are darker sunglasses worse for your eyes?

I recently saw a health show on TV that said you should wear darker sunglasses because they filter more light. Previously, I had heard that darker sunglasses cause the pupil to open wider and make the eyes more vulnerable to harmful light; ergo, you should wear lighter sunglasses with good UV protection. I have very light colored eyes, so my eyes are especially vulnerable to harmful light anyway, which is why I really want to get this right. Can you give me a definitive answer on this one?


Is male virginity detectable?

1) Simply I want to know (excuse me for my english, but I'm an Italian boy) how a male can be recognized as virgin. My friends say that the frenulum broke when you do for the first time...it's true?

2) I was reading the question about male virginity recognition and got a doubt. Is it possible to detect that a man is virgin of anal sex, i mean, has ever done anal sex?
