It's just when people say: 'go left here' or me throng to indicate direction in a split second that my change of getting it right reduced to 50%. My brain doesn't grok that left right isn't absolute but related to orientation.
What helped me as a kid is imagine to write. That's my left hand and than I know which is which without thinking too consciously (in case you're right handed, it's the other way around obviously).
But interesting that you know absolute directions easily. That's a cultural thing actually. I think Australian Aborigines will say things like "my western foot hurts" because it's more intuitive for them that way.
If I think for it for s second I know, I'll think about my dominant hand too (although my dominant feet is on the opposite side so I don't have a clear dominant side).
Yeah the aboriginal method seems way more intuitive to me, yet it probably won't replace the left right system anytime soon :p
