If he skis with a bent knees style, he will be more able to absorb the bumps. I need to ski with both bent knees and shoulders forward so that my spine can absorb the bumps and chatter.

I hear that half of the California ski professionals are up in BC. My daughter teaches at Sierra Tahoe on the single ski run they can cover with man-made snow.

Glad to hear about heading. He should never head the ball.

My first concussion was falling down the stairs at 8 years old. My second at 10 from a bike accident. Then, I played soccer for 7th, 8th, 9th and 10th until subconcussive impacts from heading the ball very infrequently crashed my academics and changed my life.

Soccer players who routinely head the ball have been measured to have a 10 point lower IQ score than those who don't.

I hope he is not having any personality changes from his concussion. I became ornery. I went from being everybody's friend to nobody's friend in short order.

Does he play ice hockey? It is very risky too.

My best to you both.
