Falling down three steps from my back door to the footpath (a house I'd lived in for over twelve years prior to this). I was concentrating on what I was doing and I was also completely sober, so I have no idea what happened on my part aside from being a moron.

What did end up happening medically was I broke three bones in my ankle, had to have a decent chunk of the rest of the year of work and still have issues with mobility nowadays even two years later.

My surgeon said to me at the time he was seeing me, "congratulations on breaking your ankle in possibly the worst way possible! Also for the arthritis you're almost guaranteed to get!" (We had a similar sense of humour, so I found it rather hilarious. Or maybe I was high on pain meds. Either or.)

All in all -- 0/10, do not recommend.
