Let's have a rare old time
Don’t worry, it really isn’t that bad once you cross the energy barrier at the Age Which Shall Not Be Named. I’ve survived for a year and a half so far, and except for sudden, inexplicable urges to yell at the neighbor children to get off my lawn it isn’t bad at all.
As far as warriors of a certain age, if any mujahideen crossed my elderly relatives they’d be eating their dinners off the mantel for weeks—if they survived. It’s all in the attitude.(c.f. Terry Pratchett’s Silver Horde ..)
