Me and my Dad are both 5’ 7".

My grandfather and uncle were both 6’ 5" and my aunt is 5’ 11".

I’m pretty sure they all had the same father as other than my Dad’s height they all look very similar to my grandfather, as do I.

Me and my Dad both started smoking pretty young and my grandfather, aunt and uncle never smoked which might have affected things.

But these guys look nothing like each other.
