4. Spend three nights in Vegas
Any octogenarian can handle two nights in Vegas -- for proof, go to Vegas, make friends with all the octogenarians you can, and see how many of them end the night saying, "See you tomorrow night, Billy!" even though your name is Steve. A three-night stay, on the other hand, is something you just can’t endure after a certain age, a grueling gauntlet of fun that will leave you bruised, battered, and in possession of a shady limo driver’s personal cell number.
