There's been a fair bit of research on that topic. Largely the studies I have read have found that especially in creative intellectual labor (perhaps some programming could be excluded), overwork leads to negative productivity, compoundingly so in the long term.
Unfortunately, the edit window has passed. I didn't mean it as a swipe but I can see it being read that way too easily, sorry dang and everyone else. You would be welcome to remove or edit that sentence.

That's a great change which totally solves the problem. I've merged it in your comment above. Thanks!
Edit: I of course believe you that you didn't mean it as a swipe. The trouble is that these things can all too easily land that way anyhow, since intent isn't directly readable. Past posts about this in case of interest: https://hn.algolia.com/?dateRange=all&page=0&prefix=true&que...
