Always sad to lose people.
RIP
Well not really. I asked a friend a several years back how long he wanted to live... he said to 100. I told him "Be careful what you ask for". He passed away recently after suffering with emphysema and COPD for a couple of tough years.
Kirk lived an exceedingly long life, most of it in good health, and contributed to the lives of millions. That's a deal nearly all of us would sign up for.
