Also access to shaving products and accessories is getting easier. Hand held electric razors are getting smaller and can do a lot of the work before a blade makes a smooth finish.
That said, as a male i hate shaving my privates smooth. I find the hair acts as a natural lubricant, without hair everything either gets sticky or feels slimy down there.
This is my problem. I love reading some denser scientific or social study stuff but sometimes just a few pages and my brain is burnt out. I could keep reading further but at that point i don’t retain as much because I’m still fleshing out the concepts and ideas from earlier.
