I was just thinking earlier what it would be like to be 1500 years old. I mean, Gandalf must have had some serious orthopedic insoles in his boots or something. People start losing their teeth at what, 65? He has one of the loveliest smiles in all of Gondor, Rohan, and the Shire put together! And watch him run when the Balrog of Morgoth is chasing him through Moria. That dude is bookin. He must run like 10-15 miles a week. Not to mention he has smoked pipeweed the entirety of his time in middle earth. So much for tobacco causing lung cancer. He doesn’t even have the slightest smokers cough.
So yea that’s what I think about if left alone for too long.
