I'm in an area where lots of wealthy families live and the average height for white men 18-24 years old is legitimately 6' tall. Someone in this sub told me 5'10 is tall and my immediate reaction was that they're retarded. Maybe I'm in a unique environment though.

Look at this graph, the average height for a 19 year old in Europe is 6'0 in most countries!
