Remember, this is the age where Kobe literally retired, sure he had a 60 point game on his last game, but that wasn't really that much of a real game and he had like 50 shots that day, Lebron did it at the same age, while averaging nearly 30 points per game. He is averaging nearly 30 ppg at age 37, can you imagine how hard that must be? Probably the highest average at that age, haven't checked but I am 99% sure about it.
Still Lebron gives an impact to the NBA game because he is one of the legendary like they are trio of the legendaries with Kobe, and Jordan so i guess if Lebron makes a retirement it feels something lack in NBA heart, well its still good if he still can to play we know its passion and full of commitment we can't remove this into a humans hobby so he will continuously play and give a good performance to its team and audience. Looking forward for more games!.
