Over 45 years ago, I started donating blood while I was in the military. I am a regular donor and donate every two months like clockwork. That is unless something slows down the clock such as cancer. I've had cancer three times in my life, and each time, I had to stop donating for at least a year. Now, I'm  cancer-free and love to donate. I have also donated platelets and bone marrow. I hope I never have to stop donating again.
