So lasers aren't evil anymore?

At my niece's school, they still use red and green markers. She's never mentioned it being hard to see. Might not be a huge deal.

Seriously? Do they actually change how you walk, or just make each step easier?

Got my partner to try poles after years of refusal. Turns out they help him stop overthinking every step, lets him just hike.

But don't old tools just wear out over time? Newer models tend to work without those hiccups.
