My entirely unscientific theory is that like other cells, we're born with a limited number of fucks in our body.
When we're young, we (instinctively, subconsciously) feel like our fucks reserves are plentiful, so we give a fuck about a lot of stuff.
As we get older, our reservoir of fucks gets progressively depleted. The fucks are rarer, so we give a fuck less and less often. I've recently turned 40 and I can definitely feel this in myself; just like recovery from workouts takes a little longer than when I was 20, I don't give a fuck about things so easily.
By the time you're officially old, you're almost out of fucks, so it's not like you don't give a fuck because you don't want to, but because it's more difficult physically (harvesting of the last fucks takes more energy, because biology).
