Feels like home wasn't until my late twenties , early thirties,till right left became more clear....Fricken door knobs made lttle sense to me . But in my defence had a bit of ambidexterity going on.....Really made my time in the military,
all kinds of weird. And figuring patients left and right was a thing you do not mess up on . It was easier for me,to figure somebody else , rightside/leftside ..but on my own still have days where I think twice.
. Port and Starboard was easier for some reason. But did get easier somewhat, after getting dominant side disabled in a major accident,Years later. .
