Why is alcohol so deeply rooted in our society?
As already pointed out, alcohol consumption, among other common insidious parctices, is a breadead easy way to iron out stressful periods, but it's not the "objectively" correct solution. The alternative is too difficult i.e. being healthy (fitness, diet, sleep, socialising). If everyone on Earth were even slightly better, these cultural indulences would disappear, but everyone would appear robotic and liveless. There's a lot to unpack when it comes to conventions of such large scale. I mean, its not hard to imagine what you should be doing yourself, but there's no way of exactly realising it.
