I used to take hour long lunch breaks, which I'd spend about 35mins walking to get food and finding a nice spot to sit outside, most days I done this I would come back into the office refreshed and often fix the issue I was working on shortly after coming back. But the hour-long break was always founded upon, which is why I ended up leaving. (it was also the only break I took each day, but the culture in the team I was in was to take no more than 30mins break)
