That is great, evolution always find its ways to get rid off the weaker population. Wearing a helmet (a good one) can save your life.

Some details:

"Is there evidence that helmets protect brains and heads? We have a statistics page that may help you research that. Don't miss the recent New York City data showing that 97% of their dead cyclists had no helmet."

I know what a data scientist would say, correlation is not causation.
