Our brains are like children, they can’t focus for long on one thing.
25 minutes is the maxium.
So any thing you pursue, from reading a book, to doing a craft, practicing a musical instrument, drawing, working, exercising, stop after 25 minutes.
Stop and move around. Look at something else. Shake your body. Get a change of scene. Go outside. Take a walk. Buy an ice cream. Drink a glass of water. Pet the cat. Do the dishes. Clean the litter box. Go pee.
I am so bad at doing this I have timers all over my house, all set for 25 minutes. I get so absorbed in my projects that hours can pass and then I hurt my brains. There aren’t too many of those precious cells left!
And what would be the point of doing something for hours and hours without a break? You want to prove that you’re an idiot? I know, there is something macho here, and I’ve been guilty of it myself. But I am older and wiser, okay? Your body and brain need a break.
If sex were still an issue, I would say maybe go a bit longer than 25 minutes, maybe less. Sorry guys, sex can get boring after that. I don’t vote for all that tantric stuff. Like my friend used to joke; want a sixty second romance? Got a minute?
No, I would not set the timer for sex. Although it’d be a good laugh.
The timer is to make sure you take a break, not set a record on how fast you can do something.
