Do senior citizens use M4/3s?

I stumbled across this other thread asking whether professional photographers use m43. But obviously not many are interested in becoming a professional photographer.

On the other hand, it is my understanding that most people do strive to become a senior citizen someday. It's a personal accomplishment everyone aspires to achieve.

However, my granddad laughed me off when I showed him by GM1 - saying he couldn't possibly use that tiny di...splay. He wears bifocals and much prefers the 9.7" screen on his i-pad.

Yet looking at the pictures posted in this board some senior citizens do seem to use m43. So, are there many of you? Do you have excellent vision for your age?

Please discuss.
