older people have money...

beer arm lifter.

grocery bag arm hooks.

dance instructor with couples integration for toe avoidance.

seat getter outer. (and toilet sitter downer)

Why just the old? I’m “young” and could benefit from an iron man suit

the difficult part for the elderly is how to put it on, the product assumes always someone helps with it, also the weight itself could be a safety hazard

make it double as an attachment for a stairlift and you have a seriously good product on your hands

a prosthetic?

A pair of skis that have a core that can stiffen under stress, bend or chatter would be interesting too. Wearing exo legs while skiing may work for some, but I think would take away from the fun and challenge. I suppose it'd let a person ski faster, which in turn would warrant the variable core. Wouldn't want to fall though or would the exo legs act as a protective mechanism? The material in the core could also be in the exo legs, like a variable turbo-charger.
