What to do during break from work?

Walking

I try to go for a walk every 50 mins, sometimes eat a snack or stretch a bit. But I don't have a system for it.

walk

Listening to some tunes, my dude.

Go up and down the stairs

I used to take long walks on my breaks, scarf down my lunch just to have more time.

Chit chat with co-workers about non-work/technology related topics. Football/sports, house, family, kids, politics etc etc.

I take a walk down to my local coffee shop and get an espresso

Make tea. I like the ceremony of it. It’s during these repeated actions that I let my mind wander and think about next tasks and new ideas.
