When elderly people stay active, their brains have more of a class of proteins that enhances the connections between neurons to maintain healthy cognition.

I was about to write a snarky comment but I forgot what it was.

How much exercise are we doing in this new year?
My walking routine needs improvement. I was getting out 2-3x week before I stubbed my toe. Resistance and light free weight work dropped from 1-2x week down to…zero. I just got plain lazy. For the new year my plan is get back to walking 2-3x and weights/resistance 2-3x a week. My plan was to rejoin the Y but there’s too much virus out there now so I’m holding off.
A lot of my friends like using those resistance bands. I have never tried them. I have some dumbbells at home. And I walk every morning. For me the key is habit and routine, so I’m doing stuff without having to think about excuses why not to do it.
One of the kids left a nice resistance band at the house which sat in the garage for years. After I quit my Y membership in Pandemic year one I started using the band. I like the resistance band. We also have dumbbells in the house. The heaviest dumbbell is me who continually comes up with excuses not to exercise.
I think the biggest obstacle to exercise is getting started. LOL
That’s me!

I thought this article was interesting.
I did too so I birded it. BTW the reason why I never saw your (or anyone else’s) comments on Twitter was due to Notifications being turned off. I turned my Notifications on. Fixed!
Yay!
