O Rh + blood type, been donating regularly for about 4 years. Feels good to know that I'm having a positive impact on people's lives. I may end up falling into the "unable to give blood due to medical reasons" category eventually. The last time I gave blood, my heart rate was at 43bpm. (the minimum required to give blood is 40). The reason why my heart rate is so low is because of my cardiovascular fitness, which I've been steadily improving upon since I started working out.
Although I suppose I could get around the "heart rate too low" thing by doing pushups or something just before giving blood.
