Young guys with hairy chests

I will never understand that trend of shaving the belly (or shaving it except for the happy trail below the navel) but leaving the chest hairy. Looks so unnatural and weird. Of course there are many men have a natural hair patten like that (hairy chest and only a happy trail below the navel as the only belly hair), but you can always recognize the difference towards a man who has more hair on his belly than just below the navel but shaves it, as that southern border of the chest hair always looks too sharp and too contrasting with the shaved belly skin below the chest, which creates that artifical look.
