That's the title of an article in the Telegraph by a Royal Marine who lost his leg. Here are a couple of excerpts.
2. Kids will stare
Much to their parents’ embarrassment, children are welcomingly tactless and often stare open mouthed before pointing out the obvious.
I smile and reassure them I am aware that my leg has fallen off and my offer to give them a detailed look at my prosthetic is rarely refused. However, I’m glad to say I’ve yet to fight a seven-year old for my leg back.

6. You will forget that it’s gone
Protracted wearing of a prosthetic can be painful, so I usually remove it when seated. This habitually results in me falling over when I stand back up as I keep forgetting I don’t have a right leg any more.
Conversely, when sat down I instinctively stretch out my missing leg to stop my prosthetic toppling over. How ironic.
There's more at the link. Interesting, often amusing, and thought-provoking.
Please God none of us will end up in a similar situation; but if we do, this man's advice might be worth hearing. I imagine Murphy's Law and Joel, each of whom has lost a leg, will probably have similar things to say.
