Those are really good tips! I haven't heard of almost any of them before 😳.

I found the 30 minute blocks idea the most interesting, I will definitely try that out myself at work.
I already sort of do this type of excercise, but I haven't given it any structure. I take many small breaks throughout the work day, but these all vary from 2 minutes to 30 minutes randomly and I don't do them every half an hour.

I very much value keeping the brain excercised and sharp, so I will not hesitate to try out any tricks to help with that.

Luckily I have a very lenient job, so I could try out all of these ideas, maybe not the 120 seconds jobs one, but I will slowly but surely get to them, if I don't forget about the tips 😅
