Any Oxford folk remember how we used to dance "Black nag"? We learnt it last night, from the original 17th century instructions, and parts of it felt familiar, but parts of it didn't. I definitely remember the "GALLopy gallopy gallopy gallopy; GALLopy gallopy gallopy gallopy; GALLopy gallopy gallopy gallopy; All. Turn. Round" bit, and the "CORners cross (3, 4), CORners cross (3, 4), SIDES cross (3, 4), All. Turn. Round" bit, but I don't remember the siding, and I can't remember any heys, though Pellinor thinks he can.
(You can tell that I used to teach these dances in my Oxford days, since I can't dance any of them without chanting the moves out loud.)

Date: 2006-10-31 10:27 am (UTC)"In adults, levels of T are very different between the sexes. Free testosterone is easily 5-6 times higher in men that women, with no overlap in the healthy population. I assume similar numbers will apply to total testosterone (most testosterone is bound to carrier proteins). From my recollection, in prepubertal children, the titers are pretty much similar (and low). During embryonic development, T is again higher in males than females (because it is produced mainly by the developing testis). However, I don't know if ANYONE knows numbers for human embryos (although I'm sure a lot is known for mice and rats). In development, T often has its masculinizing effects on the brain by being converted to Oestrogens (oestradiol) by a hormone called aromatase. This happens locally in the brain. The reason why circulating oestrogen does not have this effect is again due to binding proteins (alpha-fetoprotein), which prevent oestrogen from reaching those tissues if it originates in the bloodstream. This protein is turned off at post-natal day 7 (I'm not sure what species this data is from, but I think it's humans)."
"As for tissues: T and E [i.e. oestrogen] circulate in the bloodstream (bound to carrier proteins typically), and because they are lipophilic, can cross into any tissue (including the brain) freely (at least the unbound portion). So I expect tissue levels to be fairly similar. What does differ is the distribution of receptors throughout different tissues. And as said above, you do get higher local levels of E where aromatase is present (conversion from T)."
So, it sounds as if there is essentially no overlap, certainly in adults, and probably in utero too -- quite different from height. Interesting. Hope this is of some use to your Dad!

All turn around
Corners cross (tum, tum); corners cross (tum, tum); centres cross (tum, tum)
All turn around
Figure of eight bit, each side in turn, while the other side jiggles about on the spot looking attractive. All turn around.
And then gallopy gallopy back again.
Didn't know it had a name - always thought of it as "the gallopy gallopy one".
