Are you the type who code for more than 3/4 of the day 18+ hours per day
Even if there are people who code for 18 hours a day, that level of performance is simply unsustainable and eventually they will stop working.
You mentioned the burnout syndrome, and that is exactly what will happen if people don't take proper rest.
I concur with you @dedicatedguy, nice to see you here.
18 hours per day is impossible for one weeks on more. Then, your code is less productive.
Of course, though there are people who are so addicted to programming to the extent that they care less about its consequences. Nice to hear from you @napotem.
