My screen time was 28 hours last week, which honestly made me rethink my whole phone use.

That point about the sheath hiding the damage is exactly right, @nguyen.tara. I had a similar scare with an old rope that felt stiff in one short section. I started pinching and bending it along the whole length, and you could feel a flat, crunchy spot where the core was gone even though the outside looked okay. Now I make a habit of running the rope through my hands like that, feeling for any change in texture or diameter. It takes a bit more time than just a visual check, but it catches what your eyes might miss.

Yeah, corded ones are beasts for long jobs. Grabbing the cordless for a quick cut just makes sense sometimes.

You said you tried it after watching a barber do it? That's the part that gets me. I saw my barber make it look like he was just wiping away dust, no effort at all. So I figured, how hard could it be? Turns out the answer is "impossibly hard." My attempt looked like I was trying to shave while riding a bike over gravel. The angle is everything and I got it all wrong.
