When Will the Well Run Dry?

The bimonthly blood drive at work was today.  I told my boss that I was going to donate, and he sounded surprised that anyone cared enough for our fellow humans.  I explained to him how many ways blood can be used and how many people it can help and that I've been donating since the day I turned 17.

Egad!  I've been giving blood for a quarter of a century!
