Sorry to be serious when u are joking around, but these athlete who do extreme endurance sport are generally not the pinnacle of health and will not age very well.
Their cortisol levels are consistently elevated beyond the normal range, very low bone density and fragile, a lot of hours under the sun's rays with minimal sun screening, under and over developed muscle groups in different areas. Extreme metabolic rates as well.
People like Vincenzo, Bala, Gilbert, Rebellin are legends and have great longevity on the bike, but in normal clothes in November they look well beyond their age.
And then there is Pozzovivo who still somehow look 18
