Settle an argument - can you form a straight line from knee to toe?

[GimmeAy]

Weird title I know. Apologies.
But myself and OH were just discussing my legs. Or more specifically my foot.
I was stretching my leg/foot out (as one does) and he jumped in horror saying 'Ew, that's disgusting?' After much questioning it transpires that I can bend my foot down enough with an outstretched leg so that it's just one straight line (hard to explain).
He tried it and his ankles won't go halfway near to a straight line with his leg.
Is it men? Is it me (dancer all my youth) or can everybody but him do it and I'm not a freak?

Side ways

Yes. But I can also bend my elbows back at right angles and my fingers backward, years ago classed as double jointed, but hyper mobility.
One word of advice to all the younger mumsnet people, if you are hyper mobile, please dont exploit it, I used to as a kid and as an adult and my joints are shot to bits now, I'm 54 and not much was known about it years ago. I loved making people cringe and tell me how amazing it was.

Ruby yes 50s here and suddenly swinging my elbows 360 degrees and bending my fingers back isn’t quite so funny. Photo of thumb bent to touch wrist

I can. I’m hyper mobile though. When I lay on my back my feet sort of naturally flop into this position. It feels weird and unnatural to have my toes pointing straight up.

I absolutely can! Ex dancer.
