Oh, to be young again and when you can fall asleep without a busy mind keeping you awake.
Back then, I was practically always dead asleep within minutes of my head hitting the pillow and a snooze was always within easy reach no matter when I tried (wasn’t uncommon to have a 1-2 hour nap after coming home from school). Flash forward 16 years to today and getting to sleep isn’t too much of a problem but it’s much more common to have trouble with getting my head stopped long enough to drift off, especially nights when I don’t make a point of doing almost nothing for 2-3 hours prior to wind down.
But also, as I get older I worry less about my own mortality - me, you, everyone we both know - all going to die, and worrying about it isn't going to change that.
Podcasts do sometimes work for me and I have some sleep meditation (yoga nidra) stuff I listen to as well. Combined with the odd supplement or medication, I can usually get some sleep but I’ve yet to find a silver bullet.
