I mean, yeah? But if I sleep 8 hours every day, it's not like I'm going to just naturally go to bed at the same time every day, usually I'll go to sleep 2-4 hours later than the previous day and naturally wake up 2-4 hours later as well. If I don't sleep that well I'll then go to sleep earlier the next day. This is quite problematic because of 9-5 shit, but rhat's why both sides of the sleep schedule have to be enforced.
