Might be an idea to get Jen a wheelchair. My missus was told our local hospital could "lend" her one, but they'd have to charge for it! She found one for about £40 so she could at least get around the house. She also bought a larger motorised one for shopping trips etc. as she lives on her own.
There's an idea for you! How 'bout leavin' Jen in charge of the kitchen and you could pimp her wheelchair by adding say a V-twin motor, air horns, alloy wheels and sports exhaust! And don't forget to include retractable sword blades on the wheels for those ignorant pedestrians who just won't get out of her way! And maybe a couple of RPG launchers on the back for motorists who won't let her cross the road?
