Just as a fault check, 0.53 deaths per million hours of living implies a median life duration of 215 years by my napkin estimate? It makes me say "hmmm".

I agree with Chalo.

365 days * 24 hours * 100 years in a century = 876,000 hours per century
1,000,000 hours of living and 0.53 deaths = 1,886,792 hours per life span
1,886,792 / 876,000 = 215.387 years of life
And if that is a Median, then 50% lived shorter than 215 years and 50% lived longer than 215 years. Cycling is healthy so the cyclists were probably in the longer than 215 year lifespan group.
