Firstly, people generally lived much longer than 20 years of age 200 years ago. Jesus was around 33 years old when he was crucified . Ever since then living conditions and quality of life have increased which also raise the chance of living longer lives i.e. people washing more frequently etc.
Instead of turning to drugs to get rid of any stress you have, why not turn to God? Why?
Here is the answer to all of the above and it's not drugs:
Proverbs 3:1
My son, do not forget my teaching, but keep my commands in your heart, for they will prolong your life many years and bring you prosperity.
I totally agree that turning to God is a good answer but that does not negate the realities of this life. you dont quit your job and say God will provide. Im not saying we should all go out and get stoned but I do believe that there are some people in tough situations.
Also in regards to back in the day since everyone wants to go there, most everyone was working to live, everyone was doing it, other than maybe the king and his entourage, now days you may have a neighbor that is going on vacations and has toys etc so not all are sharing in the toil and its not a way of life of the commuinty, you can call it pride or envy or whatever you want but when you see how life can be but its not your reality that creates ALOT of stress, not that you are jealous or want to steal your neighbors stuff but its impossible to not think why do I have to live like this when the guy down the road has much more ammenities. If we were ALL toiling like in the day it woudl not be an issue, everyone likely wrote off the king because he was the king and most did not even know what he looked like or where the castle was. When you feel like a slave to your neighbor thats a serious issue. Maybe you are raising 2 kids on your own with your husband and the guy down the road has a nanny, this sort of thing did not happen back in the day, very few had knowlage of the better life, once you have seen or tasted of that life style there is no going back.
So you can not compare people 2000 years ago to today, I can look back within my own parents and grandparents life times to a day when life was easier, we have alot of added burden from 50 years ago. Lower pay for the same work so both parents have to work (higher cost of living), the social structure for kids is broke leaving parents to have to pay for expensvie day care etc. The mom can not stay home becuase one income does not cut it if you want to have any sort of life at all and have anything nice. Heck my grandpa was able to buy an air plane and hunting rifles on one income with 3 kids with no silver spoon, that would never happen today, I dont care how many degrees or certificates you have, almost no employer pays enough to rasie 3 kids and have a stay at home mom and buy a plane. The pay is just way to low these days and the stress is way to high.
Granted some of that stress is from poor life choices, but once a poor life choice is made you have to do the best to live with it and I can picture scenarios in my head where I would not begrudge someone from checking out, kids screaming and running around after a 10 hr work day coloring on the wall and you just want to check out.
