I understand that the average lifespan of a horse is 27 years with a standard deviation of about 4 years. Thus, it is pretty rare for a horse to live past 40 - but the Guinness Book of World Records says there was one horse named “Old Billy” that used to pull barges up and down canals in England. That horse was born in 1760 and lived to be 62 years old. I had a medical appointment on my 62nd birthday and the doctor said I was healthy as a horse. That’s when I decided to slow down. I want to be healthy as a giant tortoise.
