I have no major age complaints, though I'm not so naive as to think they aren't coming my way if I live long enough.
Most of my complaints are annoyances rather than quality-of-life issues:
It's a rare night when I get more than six hours of sleep - and glorious, uninterrupted sleep is mostly a thing of the past.
Regardless of outdoor temperature I bring a sweater anywhere likely to be commercially air conditioned, grocery stores most especially.
While I remain pretty limber and have no trouble getting up from the middle of floor (so no chair or other means of assistance), my balance is definitely not what it once was.
Some jar lids are very difficult to open.
I need fairly strong reading glasses (2.50), but don't need distance glasses.
It's often hard to discern what someone next to me is saying when there's a lot of ambient noise.
Generally speaking, my upper body strength isn't what it was even 10 years ago.
