> expectations to be successful

+1. Also maybe it's an age where responsibilities start to peak. More senior positions in the workplace, having children, marriage, etc.

I've had a few stressful periods lately where it felt or feels like I can't load any more on to my plate and I don't even have that many responsibilities - no kids either, just an accumulation of small and background things needing dealt with. I think I do understand people who do commit suicide to an extent - if you add the above normal stresses of life to some highly stressful life events like a breakup or divorce and throw kids etc into the mix - and hey why not a pile of work related stress too - I can absolutely see how people get pushed to the edge.

Modern society has not been arranged in a way that sets people up for success. Staring at device screens for more hours year on year likely doesn't help.
