Video games are even a physical activity nowadays so how does that work?

Having sex takes care of both of those activities.

And what about the ones that just lie there like a corpses?

Did Grandma say this while banging a guy she picked up at the gym?

No while she was showing the parents her light up vibrator.

demonstrating while she was visiting them at the cemetary

No, probably whilst he was scrounging up doritos and mouldy cheese off of the bathroom floor.

I'm surprised OP could hear her with that mouth full of nachos! "Mhmmph Now where are my pants.."

At least she kinda covered for you lol

Sex is a physical exercise. Go get 'em, girl...

Cougars these days.

Yeah, and what about you, Grandma?

That's a question who's answer I would not want to hear.

Go bang a dude on a treadmill and kill two birds with one stone.

Or just ride a space hopper to a similar effect

A space hopper/dildo combination...hmm...to the patent office!!

Dildopper!

Nothing quite cures the burn when delivered from Grandma.

Grandmas: calling it like it is since they stopped giving a fuck.

As Olivia Newton-John says... Let's get physical physical!

Er no. Just no.

You just got owned by grandma.
