Warning about ALYX blood donation!
how did you find out you will take a couple of weeks to a month to recover? Is that how long it takes for the body to regenerate thos eblood cells? and what other effect does that have on you? Why did you do that? There are plenty of non-athletes for that aren't there?
I'm just selfish enough to let "them" die, and save my friend.
The 2 - 4 weeks is just a guess. When I give whole blood, I feel fine after a day or two. Maybe I'll be fine in a few days.
the blood generates new blood cells very fast. I'd guess tomorrow or the day after you should be fine. (I think the bone marrow produces like 2million red blood cells per second, and I can't remember how often all our red blood cells are exchanged for new ones, but it's often.)

I am feeling much better, 4 days after the ALYX.

3. Therefore, 30,000,000,000,000 / 120 means 250,000,000,000 red blood cells must be produced each day to replace the old red blood cells
4. The body can produce 2,000,000 red blood cells / sec, which comes out to 172,800,000,000 / day.
Thus, at these rates the body cannot produce enough to replace the old red blood cells, much less the loss of 45,000,000,000 red blood cells that I donated.
Either Wikipedia's number are screwy or something else is screwy.
I registered to say: your math is wrong. 30,000,000,000,000 / 120 would get the number of cells your body needs to produce every 120 days, not every day. so 250,000,000,000 / 120 is 2,083,333,333 cells per day that your body must produce to survive. I realize I may be a couple years behind on this conversation, but just wanted to clear it up. Bye!
Your math is incorrect. If your body has 30 trillion blood cells, and they live 120 days each, then 1/120th of those cells die every day. So 250 billion blood cells per day is correct.
