Popa: To be blunt, your post disgusts me. Completely and totally. As a human being as much as as a frum yid. How can you ever ever talk like that? It is rishus and selfishness through and through.
It doesn’t even hold a candle to birth or kindey stones or anything else. Its a pin prick. Thats it. Like any blood test. It just takes a little longer is all. There are absolutely no side effects (you might feel a little faint or weak if you haven’t eaten). I have donated twice. Once through a bikur cholim, once through NY Blood Bank (it was convenient). I wish I had more opportunites as a healthy adult can donate every 4-6 months.
There are too many people who are not allowed to give blood for healthy people to shrug off this easy, lifesaving, free (for you) donation.
As to personal gain – who cares!! You are helping a fellow human being. and Panni55: No, I do not believe there are any health benefits from donating (blood letting as a practice was stopped way back when). Iron is good for you!
PBA: I really hope you rethink about this.
