Yesterday I went to the doctor...

Yesterday I went to the doctor for my yearly physical. My blood pressure was high, my cholesterol was high, I'd gained some weight,and I didn't feel so hot.
My doctor said eating right doesn't have to be complicated and it would solve my physical problems. He said just think in colors; Fill your plate with bright colors; greens, yellows, reds, etc.
I went right home and ate an entire bowl of M&M's and sure enough, I felt better immediately. I never knew eating right could be so easy.

William Ernest Castle

Born 25 Oct 1867; died 3 Jun 1962 at age 94. William Earnest Castle was an American biologist and geneticist who was one of the earliest experimental geneticists. Castle's interest in natural history began as a youth growing up on a farm. From 1897, he was a biology instructor at Harvard. In 1901, he was the first to adopt a variety of the fruit fly, Drosophilia for experiments because of its advantage of quick breeding. He took an interest in Mendel's ideas, extended Mendel's Laws to mammals, and made a connection with Darwin's ideas on natural selection.
