Is knowing which way is left or right as automatic as up and down?

[Dramatic]

Saw a video online about this, apparently for some people knowing their left and right is as automatic as knowing up and down. Is this you?

I struggle so much, I can be confidently saying left and pointing right or vice versa and when someone gives a direction it takes me a good few seconds to know which way they mean. Whereas if someone said up or down it would be instant.

YABU left and right are as easy as up & down
YANBU left and right takes a few more seconds to think about/I quite often get it wrong

Tricky...I took a look at what dictionaries say for 'right'.

This makes sense to me but will leave some of you more confused than ever I fear.
on or towards the sidede^ of yourur^ bodydy^ that is to the eastst^ when you are facingng^ northth^

I'd find 'on the west side of your body when you're facing south' more useful for the daytime.

There's also of, relating to, situated on, or being the side of the body which is away from the side on which the heart is mostly located

I think I do instinctively know it - but I don't trust myself to instinctively know it. For example, when I was a witness in court I was asked to raise my right hand, which I did straight away - then doubted myself and did a silly thing where I half lowered it and half raised my left before realising I was correct first time.

I struggle with left and right..I hate it so much
