I wonder how these results would stack up against something like pro baseball players or pro cyclists - both have a very long season (6 month season for baseball, even longer for cyclists). Maybe a bit like touring bands.

Three main differences that come to mind... - athletes repeat this annually (famous touring musicians might take a year or two off to record new material). - athletes likely live a healthier overall lifestyle because being extremely fit is part of the job. Plus the teams have embedded MDs and other health support staff (some musicians will, some won't). - athletes usually retire from their primary sport in their 30s, so only ~20 years of touring on the high end, where musicians can tour into their 50s or 60s (or beyond for a few).
