This hurts nearly as much as the OP.
Middle-aged starts at 30?! Fuck I’m old. At 53, middle-age didn’t start til 45, 75-89 is old, and I’d put super old at 95+.
Then again, I may be skewed a bit since my 88 year old dad is sharper than most people I know, still works his regular job in aerospace, and drives Uber in his spare time to keep himself young. He may live to 120 at this rate.
