There has been a great deal of activity in this space especially over the last 1-2 years. There are various mHealth and digital health sites, groups, conferences and resources. I recommend you check out Aging2.com as one place to start. I have been working in this space for several years and can share what I have learned.

I looked into this a bit in connection with some of the domains I've invested in. What stood out to me is the Senior Travel sector. Realizing that people take vacations after retirement is hardly earth-shattering. But what interests me is the obvious upward trend:

(1) People live longer.
(2) They spend a greater portion of their lives in retirement.
(3) The senior population is growing.
(4) Seniors remain in good health much longer.

My grandfather just got back from snorkeling and whale watching in Hawaii. He's 87 going on 88.

Not all seniors can afford or will want to go on cruises around the world or ride on camels. But travel and leisure opportunities close to home don't need to be elaborate or expensive. Groups of seniors going to a museum or a concert or a play or a movie -- that will become an economic force to be reckoned with.

This question touches my heart both personally and professionally, and am excited for the work you are doing! If you haven't already done so, I would encourage you to look into "Aging in Place" literature and the power of blended demographics - seniors with young adults down through to young children. Denmark is making amazing advances in this direction, with layering learning across age-ranges. Within something like co-housing environments for example, when combined with augmented reality / mixed reality, could yield some wonderful possibilities.
