The way men fall asleep

Men twitch as they fall asleep.

They do it as teenagers - I remember lying on the beach flanked by male friends and suddenly feeling as though I'd stepped into a mute Tourette movie. The first of many encounters with the Master of pre-REM.

They do it as adults - and often do not even know they do it, a most extraordinary thing considering they twitch so intensely at times it is enough to pull me back from the brink of sleep (where I often teeter just for the sake of it to quickly retreat on my own anyway- case in point being now.).

And apparently, they do it all across the world.

Why? WHY?

I have twitch-envy. Trust it to happen to me.
