Wanting to do something to help in the wake of Hurricane Sandy, I went down to Gotham Hall in midtown Manhattan on Friday and, along with a motley crowd of other New Yorkers, donated blood. (I had never done this before, due to a phobia I apparently shared with lots of people, including, it turns out, several of my friends. Did you know only 2 percent of the population has ever donated blood? If you belong to the other 98 percent, I can testify that it’s not painful or scary, everyone there will be very nice to you, and afterwards you will feel brave and useful. You may even get a reward. This particular drive happened to be cosponsored by the Yankees, and I was given a voucher for two tickets to a Yankees game. In my case this was like giving a cat a box of chocolates, but still).
