So much genuine amazing feedback, thanks so much..

I have been doing this job 20 years now and I think this feeling is more prevalent now. The combination of family, commute, and sitting at a desk coding is frankly tiring.

I often get up and walk around, and drink water, etc.. I cycle to work often, used to do gym sessions at lunchtime And that definitely helps..

But sometimes when you are thinking intensely you just zone out...

I used a little poetic license regarding "I wouldn't drive" just to get my point across.
