Of course you want to donate for the altruistic benefits. But there are many other important benefits. It can drastically reduce the risk of heart attacks for men. Cancer for men. And even result in some weight loss.

These things occur with regular donations, twice a year or at worse once a year. I am now shooting for 4 to 6 a year. I just did my second one within the last 70 days.
