My family can tell you about our trip to Costa Rica several years ago for Christmas. And they can tell you about the absolutely spectacular fall I took down a set of stairs (built of polished tropical hardwood) in Monteverde. I landed directly on my elbow, and it was one of the more spectacularly painful falls I have ever had.
Last night I repeated the exact same stunt on my slick, steep basement stairs. I landed on the same elbow. Directly on the same elbow. Poor elbow.
Apparently years worth of recreational gymnastics and skiing as a youth has done me some good however, because in both cases I did not crack my head (a really really good thing for which I am very very grateful), and I didn't put my hands out behind me to catch myself (the #1 way to break a wrist) I landed on my elbows like I had been taught.
But I have to say....Landing on your elbows like that SUCKS! (and what's really entertaining is I landed on my left elbow, which I normally rest on the armrest while I drive, only now, anytime I rest it and we hit a bump it becomes a huge driving distraction.)
