ELi5: Why does drinking alcohol give you a worse hangover as you get older?

Answer 1

A few things. Things like whiskey, spiced rum, and red wine give you worse hangovers than vodka, which in my experience is more what young’uns drink. Your liver becomes less effective at filtering out all the stuff in those drinks (including but not exclusively alcohol). And finally, those things which your liver become worse at dealing with cause chemical imbalances that your brain becomes less tolerant of with age.
