Here is what I tell my wife. I do not want to live for ever. I am 66 and do not take drugs. My wife is also 66 and takes about 4 drugs. Who is going to die first? Who cares?
The comedian Alan King used to have a bit where he’d take a local newspaper and read a portion of the obit where it would say “husband, aged 86, dies of whatever; survived by wife, age 90”. The wives were always older and all outlived their husbands. It was pretty funny.
