Dick,
I love my Mum and she loves you so you can't be as bad as people say. A suggestion, how about you put your energies into the products used by the elderly ladies as you seem to have a reall connection with this demographic. Possible products could be an updated version of the Smokey Dawson self standing armchair or a lightweight walking frame made from Kevlar using aerodynamic principles. Just a thought.
