Maintain A Clean Bill of Health

It feels like the ultimate jinx to write this, but a successful and satisfying John Cena retirement tour is contingent on his health.
To his advantage, Cena has always been bionic in nature, much like LeBron James, with his unmatched longevity, minimal injuries, and insane physique. His most serious ailment came in 2007, when he tore his pectoral muscle completely off the bone. Still, Cena proved just how durable he was, rehabbing and returning three months earlier than expected to win the Royal Rumble. That’s not normal, even for a then 29-year-old.
Now he’s 47, and he’s got the mileage to show it. He competed 300 days a year for nearly two decades, traveled the world a number of times, and routinely performed in the highest intensity matches. See: the “suplex city” squash match with Brock Lesnar.
The good news is, Cena’s 36-date schedule will enable him to focus on quality of match (and recovery) rather than quantity.
