Sadly nothing tangible I can suggest doing to others. I'm not doing regular physical exercise, nor dramatically different diet. And note that my material situation is half shit (jobless, at my parents, dysfunctional family). So it's not a matter of finding a better spot either.
I guess my point is, don't underestimate your mind and capability for happiness, even in the worst of times, even if counting a decade.
My only hypothesis, is that after trauma you have a finer sense of what is good and bad for you and you kinda filter shit out (be it doubt, anxiety, low self esteem, social pressure) and think/go for simple but deeper fun thoughts/activities that tickle that sense of happiness.
ps: oh also, 30s is also an age where you usually have childrens so childhood is often in your mind. So maybe this is a normal time period to have more attuned brain toward this kind of mindstate.
