Welcome. I'm 49 now, and I took up fixed gear riding at age 40. It's quite addictive isn't it? One must wonder if the cyclists back in the 1890's had it right all along, as all bikes back then were fixed.
Of course, there is a learning curve. Some people pick up on it with a single ride, and some folks take a few weeks of nominal riding to get the hang of not coasting. It's well worth going through the learning curve though.
