Great post as usual.

Just wanted to add about exercise:

As a psychologist (now retired 1 year) I always recommended walking first to patients/clients, as it was the one thing you could be sure everyone was already doing - just had to invite them to do more (and for wheel chair patients, wheeling themselves around a bit longer worked as well).

But I would also say, there are some routines people love, who otherwise might find just walking boring (that's me also).

I love walking 20-30 minutes daily with my wife, but I would get bored if that was the only exericse I do.

So I hasten to add, I ONLY do exercise I love (so this might not appeal to you, but the idea is to find something that YOU love - if walking does it, that's great, if not, it's EASY to add more)

1. kettlebells. I just love swinging kettlebells. not only do I look forward to an intense routine 3-4 times a week, I enjoy doing 1-2 minute breaks during the day and evening (in fact, just did one!).

I like the feeling of doing resistance training. When I was younger (like, early last year, when I was still 67) I still enjoyed dumbbells. I don't feel the need to build muscle any more, just maintain what's here - so I moved to resistance bands, whichI like more.

I always have loved running, but my 68 year old knees don't love it as much, so I do brief running - about 1/4 of a mile, alternating wiht kettlebells when I work out in the mornings.

I love stretching but have never found doing yoga at home much fun, so I made a collection (hey folks, lots of great illustrations on pinterest and Google images) of about 30 stretches that I love - do them while watching netflix/Hulu or whatever, and also during breaks in the day.

Try this if you like dynamic stretching: https://www.youtube.com/watch?v=xLlE7csP1KI&feature=youtu.be
