On a good day with a decent amount of sleep, good food (not too light and not too heavy) and interesting tasks, I find that I can dive my head pretty deep into concentration and really filter out the world around me.
Doing this takes a lot from me, so it usually only lasts up to around an hour before I need a good break.
But most days, I don’t end up concentrating that hard.
It depends.
