I've just moved across country and really would not like to get a "job" so I took the opportunity to go through Dan's 48 Business ideas. Enjoy working w/ seniors and a few of the ideas I'm working on are:
1- computing w/ seniors, I've had some older friends get stuck using some programs or get a virus and can't lug their computer to a shop to fix it.
2 - checking on seniors combined with an errand service.
A marketing strategy would be to teach a class/seminar on a new program or restoring a computer to an independent living facility or senior center. I have experience and the patience working with seniors who are 85+ and losing some of the problem solving skills they used to have and have the interest in helping them be as independent as they can be.
