Yeah. Year ago I decided to take my money (over $800 including all checkups and gas) and make myself childfree.
Did doctor asked me am I sure? Yes Do I regret it? Hell no!
I had an internal giggle when I saw smoke coming from where my balls are (since procedure was painless)
Sometimes people tell me it wasn’t smart, but they have kids so I ignore them.
I really hate the thought of having children :)
I think you might be missing the point of the article. I didn’t use a specific number because people are all different and develop differently. It’s generally around the mid to late 20s that most humans brains are fully developed.
