I'm afraid of blood. I grow queasy if I hear about it or think too much about needles, etc. That's why I donate occasionally.
First, the good news - despite needing to drop 30 more lbs my blood pressure was 110/62, pulse 56, and temp 97. [this is the tie-in to cycling]
Second, the odd news - besides being O negative my blood has something called "vnc negative". Apparently only 33k people in the US are in that group. Don't ask me what it means but it's apparently a good thing.
Oh - and despite much too long a wait the donation went quickly and I didn't suffer chills, faints, or other issues. Whew!
