Back in London, like the new father of twins, with a leg tucked under each arm.

It's too early to say what I make of the new prostheses. It always takes a while to get used to a limb. In the case of the leg I'm wearing at the moment it took a number of months before I was really comfortable with it. Now, though, it feels like as snug as an old slipper.

I'll start breaking in the new arrivals tomorrow.
