I had my annual physical this week. When the doctor listened to my heart he said, "Your heart rate is nice and slow. Do you exercise?" I said yes, and he asked what I did. I said that I loved to run, but I only let myself run one day a week. He raised his eyebrows and asked why.

I said, "I love to run, but I've known too many people my age who have ruined their knees by running too much, so I only run one day a week." I went on to say that I do something almost every day. I swim, I bicycle, and I walk with my husband."

"Well," he said, "It's certainly working." I did not remind him that I was Type O, and strenuous exercise is beneficial for me. I've mentioned the Blood Type Diet in years past. He can't deny that I'm in good shape and obviously doing something right, but he can't admit that it has anything to do with my blood type.

I spent most of today sitting in a meeting, so I need to get some exercise tonight. My son is reading, so after I post this blog, I think I'll spend some time on his rowing machine.
