You're only as old as you feel.
And if you want a healthy outlet for rage at any age, do as this 68-year-old Canadian grandmother did and join your son's grindcore band!
The project started in 2015 after a viral video showing Grindmother and her son recording a song earned a puzzled Tweet from The Prince of Darkness (now 68 years old as well), Ozzy Osbourne.
If Ozzy can do it, so can she!
Grindmother even appeared on a news station in Canada to talk about how she ended up joining her son's band. You won't be surprised to know that she sounds a bit hoarse.
