When I was younger, I was prone to falling out of chairs. Backwards. I have kept up this habit to my present day.
The dining room chairs were excusable, they were very light made out of vinyl and metal poles. The band room chairs also, being plastic with a low back.
The recliner in the den proved a little more embarassing, being made for the purpose of reclining back a long distance, and being so much bigger.
I can't remember for sure, but I'm pretty positive I've fallen out of at least one of the chairs in my dorm room; if not, I'm confident I will do so at some point in the future tbs.
Also, this one was pretty amazing at the time; I was at my grandparent's house on my bike (I don't know why I had it there), trying to go up a little steep hill. Except my forward momentum did not counteract my acceleration due to gravity, and my head painfully hit asphalt. I was not previously aware that you could flip backwards on a bike, but I sure was wrong.
On one hand, I hope that my flipping days are done, fast approaching the age of fragility and arthritis as I am, but the other hand maintains that it's kinda fun, the excitement of 'holy crap no more balance' and 'lol what a dumdum', so I am undecided on that.
