I can't recall ever having sat like that in my life. I think it's a gender thing.
However, curiosity got the better of me, so I gave it a go. I doubt if I'll do it again.
Feet to the right OK, feel to left seemed odd. I'm right handed, left dominant eyed.
I'm looking forward to reading the conclusions your research leads you to.
Hmmm - Gender thing?!? Well I'm not taking offence but I guess we do live in very strange times now.
Firstly - thank you for participating and feeding back - 82 and messing around on the floor for questions off the internet ?! - You Star!!
No conclusions yet at this point - it think over long term if we 'favour' a seating position and there is no doubt each western generation is sitting more than the previous and this in itself is not healthy and will from unbalanced isometric static lengthen certain muscles and shorten others. Even in a bolt upright straight up military sitting position that would be the same , if we add in some twisted torqued seating over time I think we can mess up our natural body alignment.
As mentioned I had to rehab this and change my behaviour so I now try to as much as possible sit consciously in a very neutral position or sit on the floor on a 'L' position.
I try to sit and get up from the floor with legs to either side and the fact one is far easier too achieve than other tells me there is something off and unbalanced.
