Your intake of sugar participation in extreme sports absolutely impacts other people when you end up with chronic health issues that other people have to help pay for.
It’s not as if there’s some natural law obligating you to pay for anyone else’s health issues.

If you don’t like it, insist that people pay for their own health care and insurance at market rates, without subsidies.
