I visited my regular doc about something and he was examining my throat. He said, 'I don't recall you having your tonsils removed'. I said, 'I haven't'. He said, 'Well, you don't have any, or they are so small that I can't find them.'
I too have very strong bones and have never broken anything, although the opportunity has arisen more than once, especially as I fall over my own feet. Their density and my large muscle mass probably account for my weight (I take a UK size 10, but weigh 154 lbs). I was being fitted for a corset yesterday and the lady told me I was one of the tiniest customers she'd ever had, which is strange as I'm at least 20lbs overweight, according to my BMI.
And I have a high arched palate (it's fully formed), or so my orthodontist told me.
My hair, nails and skin grow quicker than most people's (need to exfoliate a lot or I get ingrown hairs).
I also have a weird anomaly, which is fairly rare. I was born with a hole in the skin at the base of my spine. I've recently discovered (from watching a medical programme) that this is the remnants from where our ancestors had tails.
But, I'm not double jointed, in fact my joints are naturally quite stiff and only supple because I do Zumba.
