In my experience, I also need slower days otherwise I will simply burn out. I love having days full of code, but this is not sustainable. After 8 hours of coding and focused work, I typically need a day or two of recovery. I still can perform tasks and plan but not at the normal intensity. Another approach is 4 hours a day of code daily. This can become a problem if you have a 20 year old team mate willing to grind 12 hour days and just knock out all the tickets. This can create toxic behavior and resentment from that individual towards older and experience devs. In everything people do, there is time for rest or a task that is easier physically or mentally. A laborer cannot sustain moving shovel non-stop all day. A soccer player cannot sustain playing 8 hours a day. This is part of being human.
