As previousl people have said, he needs a 2 week break from his heavy 11 hours a day 7 days a week schedule, after every drop.
Except when he needs to take time off in the middle, to move, get sick, have to go places for extended periods, have broken pc problems in a world where things get delivered the next day but it takes a month to fix, christmas, easter, ramadan, chinese new year............
Lucky for us this means he'll have a 2 week break in time for a 4 week christmas break, followed by some short sickness, australia day celebrations, then we're ready to start the much quicker development cycle of 2022.
