And I'd walk the house to new places.
Kinda like a hamster ball, but for humans.
Don't know about a 'rolling house'; but walking, running; inside a ball; might be safest option to outdoor exercising or just getting to store; someday - soon. . .
A 'security ball', perhaps?
Whatever; perhaps, in some fashion; we will all be, "rollin; rollin". ..could make running on the beach interesting. Why should hampsters have all the fun?
