Almost 39 and he’s somehow having his most efficient season ever. Looks way more explosive than he did in the playoffs and has good lift on his jumpshot again. Dude might fuck around and still dominate into his 40s.

LeBron also has greater longevity
That said being 36 years old in tennis is way more demanding than basketball. No timeouts no teammates no lazy defense and no load management

You get far more breaks doing nothing in basketball than you do in tennis
