This is a cultural, medical, and ironic addendum to the discussion.

In my teenage years I was a good tennis player and a very good ... competitive on a national level ... sailboat racer. I spent a lot of time in the sun, without benefit substantial clothing or chemical protection.

In my twenties and thirties my lifestyle changed a tad. I spent a lot of time indoors, all night, with rock, jazz, and r&b musicians, on occasion ... not when I was working for the Times, which frowned on it ... engaged in some of the vices associated with the era, some of them chemical.

So here I am at 60 and guess which of the two lifestyles has risen up with a threat to kill me?

Not a very serious threat so far, thankfully. Just enough to set off a Code Orange irony alert.
