It's the kind of re-evaluated outlook on life you only get as you grow older and you start witnessing more and more deaths and imminent deaths around you. I'm also dealing with cancer in the family (I'll spare the details), so my time really is too valuable for god damn software updates.

I'm not. Like I said, if my threat model actually incorporates the kind of threats that updates ostensibly protect against, the scales would weigh differently.
Would I keep business computers updated? Absolutely, if for no other reason than so I can make it all someone else's problem. I'm talking about my own personal computers.
