How much lifetime skating skill development could a Dominican possibly have?
I rode a bicycle without a helmet for my entire childhood. I had one bad fall and smacked my head. I saw stars for a good 10 minutes. Definitely had a concision. Shrugged it off when the dizziness passed. Only happened once. My understanding, is it only takes on good whack to the head to cause permanent damage. I can't see many Dominicans skating in this country with more than an hour or two of experience - The risks of a bad fall are highest when learning to control yourself on ice and maintaining your balance.
Your fleshy butt should be fine, but elbows and heads... Risk vs reward is up to the individual to figure out.
Ice skating or skating, period? Rollerblading/Rollerskating aren't novelties in the DR, for example. I recall as a youngster many years ago, when the Mirador Norte park first opened, I was in SD on summer vacation and had brought along a pair of rollerblades from the States, to my (pleasant) surprise, I came across many other kids at the park also rollerblading, much faster and much more skilled than I was. One of the earlier lessons I had in learning not to underestimate things in DR *shrugs*
