Grandfather died while having sex with grandmother or so she said, which I have no reason doubt her word.  Just another thing to consider when denying yourself  the things you enjoy in an effort to prolong your life.  For some of us, it just comes with age.  A blessing in disguise, just don't go crazy and get some Viagra, a health risk for sure.   

I fear people might be getting so stressed out about what they should, or shouldn't eat or drink, the stress is going to shorten their life.  :-)
