Brain wellness software

I love the idea of 'brain wellness'!  Don't we all want our brains to be well? Exercising them right along with our calf raises and seated arm curls.  But how? And with what? We certainly know that web surfing helps but there is an entire product range out there from game workstations and technology, but also software that is purely for improving mind health and vigor. For example, one of them is My Vigorous Mind both for individuals that can be tried as a one-month subscription for $14.95 and for organizations like independent and assisted living, for example. There are quite a few products and services on the market today -- I will be adding more over the coming months to this list -- feel free to comment with products you believe help keep our brains well.
