> A healthy young person might have a 10x reduced risk The risk doubles every 7 years so it's going to be ~18x between generations, and much greater beyond that. Those who are old and have existing co-morbidities are really pushing the difference as severity of disease is strongly correlated with number and severity of co-morbidities. Edit: ~18x, not ~30x. It's late here, I can't calculate 2 to the power of 4 without a calculator until I sleep, wake up, and have a strong coffee.
