personally, I love sleeping in

I'm firmly convinced that there's nothing inherently wrong with sleeping in. That's especially true in our coronavirus world, where classes and jobs have moved online and people are no longer bound to a 9-to-5 schedule. If you go to bed at 5 am every morning and sleep until noon, you have the same number of potentially productive hours in the day as someone who sleeps at 10 pm and wakes at 5 am.

Of course, you should do what works best for you. For instance: Maybe waking up early makes you feel motivated and energized. Maybe you enjoy having breakfast with your family, or you want to garden in the morning before it gets hot. Maybe, after midnight, you have a habit of just scrolling through websites instead of doing anything enjoyable/productive. In that case, sleeping and waking early is probably a good idea for you.

Conversely: Maybe you want to stay up late to play games with your friends. That's important! Time with friends is very important, especially in our current world situation. Maybe you find that nighttime is best for thinking/writing/creating/working because the house is finally quiet. Or maybe you're just energized by staying up late. That's important too. If a nighttime cycle works for you, then rock it.

So it's more nuanced than "Just do whatever you feel like." More like, you gotta examine your own rhythms and your own priorities to find what's optimal for you, but it might be different from what's optimal for someone else.

HGR's sleep cycle is different from everyone else's, because it's variable. Left to his own devices, he prefers the night, because it's cooler and there's no sunlight. (He says sunlight creates glare on screens, which makes it hard to see with his glaucoma. Also he just...doesn't like it. Weird flex, but I figure if I'm allowed to like sunlight, he's allowed to dislike it.) But often he wants to do things with friends during the day. So he cycles around. He'll be nocturnal for a week or two, and then he'll get caught up in hanging out with us or working on a project, and he'll pull an all-dayer. Then he'll swap to diurnal for a couple weeks before swapping back. It's what works for him.

I think it's kinda neat. It's like a minor superpower. When I visit Singapore, which is a comparable change in sleep cycle, it takes me days of jet lag before I can adjust. But HGR can just flip his circadian rhythm on a dime.

(Also I wish Silver would fix his sleep schedule just a little for raid days. It's 11 am in his timezone, it's not that bad)
