What people used to drink in the past,
Beer was brewed to be drunk every day. Beer was made weak so that people, including children, could quench their thirst. Water was not clean and filtered like it is today in some countries. People extracted water from rivers, ponds and wells. But they had no knowledge of bacteria or viruses. In some countries in Asia people brewed things like rice wine instead. Over the centuries East and West have followed their own brewing traditions. This affects whether people can tolerate the different types of alcohol.
Nowadays some beer is far stronger. This can have a detrimental effect on people’s health as alcohol is a poison and in strong concentration or large amounts can kill.
Drinking beer and alcohol are a personal choices. There can be other reasons not to drink, including religious and health ones. Life is interesting. Moderation is the key.
