the kids love making them, and everyone loves eating them. any time missed in wearing your elastics will only make your treatment take longer, so make sure to wear them as instructed. a few years ago, i had good speed there and felt really good on the bike. my friends and i went out of curiosity. systems learning is often labeled as peripheral and complex. once i have a hole i use a rotary tool or my drill press with a sanding drum on it to get rid of the rest of the knot.
