Not all adventurers need to be spring chickens. I like the idea of a retired adventurer gone soft from years of retirement, or losing abilities in an accident, or through some other supernatural means (like a warlock and patron breaking their pact) who has to get back into it and relearn the tricks of the trade. To that end I created a Retired Adventurer background. Take a look and let me know what you think.
