Sounds like my parents. My bro once said that our father tried his best to ruin his health and our mother tried her best to keep hers, and they both failed. I thought that was quite an astute observation.

On a more serious note, we live on a radioactive planet that gets bombarded from other radioactivity from space(esp the sun). That probably help us mutate into who we are as humans, but tends not to be good for individual lives.
