When I was in my early 20s, I was able to work (programming) for several days a week without sleep. Non stop programming. I'm now in my early 30s, and whenever I stay late programming, like half a night, I feel like my brain will explode. Forcing myself to think hard when I'm too sleepy causes me physical pain and I feel like I'll get a stroke or something. While in my early 20s I could push myself as hard as possible against sleepiness and plow through anything.

What is the reason for this? What has changed? A bit more details than "you're older" would be appreciated.

what is the evolutionary reason for being attracted to petite women?

for some reason, i'm attracted to big ass and breasts (as most men are), and the reasons there (as ive read) have to do with signaling fertility and viability. makes sense. what does being petite signal then? and why are so many attracted to petite women as well?

HOW TO IMPROVE SLEEP

No.13701514 ViewReplyOriginalReport
Has anyone read pic related? Is it good? And most importantly: How does one improve their sleep, scientifically speaking?

CONTEXT:
I bought the book, haven't started it yet, but apparently someone found a lot of problems with some claims the author makes throughout the book. Here's the link to the post detailing the problems:

https://guzey.com/books/why-we-sleep/

I haven't read the post either, I'm planning on reading the book first and then reading the post, in order to judge by myself if the criticism is valid. But I wanted to know from /sci/ if anyone has read the book, and if it is actually good or a waste of time. But above all, I guess what I really want to know is if /sci/ has sleeping problems, and what have they done to improve their sleep.

Basically I just want to discuss how to get some good quality sleep in order to perform better throughout the day. Thanks in advance.
