Sure you would, Vladik.
I go to the same kickboxing gym as a 6 foot tall Romanian bloke - quiet, polite guy with a pleasant smile. Holding the kick pads for him is quite an experience which I have to brace for and my forearms have visible bruises for days afterwards, even though I'm not exactly a small guy (a little under 13 stone, he's around 15). He cycles to gym and to work.
Now, I would pay good money to see what happens when you get out of your car and try to knock him off his bike. I'd wager the majority of readers on here would chip in for the popcorn.
