DR. MARC SIEGEL: Grandma and Grandpa are turning golden years into a high time and it’s not safe.

With all due respect to Dr. Seigel, that's a load of crap. As a senior myself, it's not a matter of 'health'; smoking, drinking -- and even marijuana -- have benefical effects that can easily outweigh the risks given our reduced expected lifetimes.

Mind your own health, doc. I'll mind mine, thank you.
