Can I donate a kidney to my friend?

I just found out that a friend requires a kidney transplant. I've heard that we are all equipped with two kidneys and can live with just one. How do I find out if I can donate a kidney? What's involved in a kidney donation? Thanks!


When should I take a pregnancy test if I have a late period?

My period is late this month, and I'm afraid that I may be pregnant. The weird thing is, though, my partner and I never actually had actual sexual intercourse (in other words, there was no penetration). I'm wondering if the wet environment could still be a risk. I'm hoping that it's due to stress and fatigue with finals coming on that causing this delay. How long should I wait before getting tested?


Are there preservatives in saline solution safe?

As an avid contact wearer, I use saline solution to rinse my contacts daily before each use. Recently, a friend told me that many commercial saline solutions contain preservatives, which could affect the overall health of my eye. Is this something I should be concerned about? The saline I use has always felt comfortable so I never thought it could pose a problem.


Why are my nipples hard?

Is there a reason behind spontaneous nipple hard-ons? Lately one of my nipples just stays that way for the majority of the day. It's irritating! Is there a reason behind it?


Is drinking tea without tea bags better for you?

You've been a hero(ine) of mine for quite some time. I hope YOU can answer this question (it seems no one else can).

I've been reaping the benefits of green tea for about a year now, and I feel great! Just recently I began opening the tea bags after brewing, and putting the tea leaves in with the actual brew and drinking the leaves as well. Does this add more health benefits to green tea? I would think so! So far, no one has been able to answer this question directly. Please let me know if you know!

Stay Awesome Alice! May your boards hum forever!


Are genes involved in schizophrenia?

My father has schizophrenia. My great grandmother was manic-depressive. What are the genetic risks of my child being schizophrenic if I have one? Are there any tests that can be done either before becoming pregnant or prenatally to determine probability? Has a gene been found linked to schizophrenia?
