My only advice is to start by approaching the problem. “Hey, do your shoelaces come untied often?”
It's like when you learn how to roll up headphone wires or properly clean glasses.
The temptation to do it for others (and get rejected) is way too high.
Then blow the droplets off both sides and let the rest air dry. We have soft water here, so no water spots. No rubbing dry with any kind of cloth.
Two cloths are ideal: one for cleaning and another for polishing.
If you're using soap and water, apply a tiny amount of soap onto both sides of the lens --- less than a grain of rice --- then apply water and rub with your fingers until clean. Skip to polish step.
If using cleaner, spray cleaner onto the cloth, NOT onto the lens. Spray onto one side of the cloth so that you have a wet side and a dry side.
(You can use water instead of cleaner in a pinch.)
Three passes.
First pass: with wet side, wipe lens in lines from top of frame to bottom. NOT in circles. (You'll spread the dirt around this way, making the cleaning process take way longer and potentially introducing scratches.)
Second pass: Repeat first pass with dry side of cloth.
Repeat first and second passes until lenses look mostly clear.
Third pass, if you have a polishing cloth: Wipe polishing clothes in circles until lenses are clear.
Your lenses will last forever if cleaned this way.
The cleaner steps above also work on any glass surface, like laptop screens or car windows.
To put it more simply, many of them will simply ruin your headphones if they're done with reasonable frequency.
For thin earbud type cords, just coil them loosely in a small plastic bag or use a loose bundle secured with a broad velcro strap.
It made a massive difference in my quality of life and I still have so many velcro straps that I find myself giving them away.
This is me daily.
It could make their lives so much better, but kind of awkward to broach. Perhaps sholladay‘s advice will work well.

You have bad laces. I thought this too before I tried different laces. Turns out different tensions and elasticities give different strengths of knots.
For example I have some military boots which came with slightly stretchy laces. They NEVER come undone, ever. They were the first pair that switched me on to this, and since then I have always bought laces with slight stretch to them, and the knots always stay done up.
In contrast when you buy a pair of fashion trainers, the laces in them are usually terrible and come undone several times per day as you have noted.
It was because I was essentially tying a granny knot instead of a reef knot and anyone who knows anything about knots would realize that of course they would keep coming undone.
And for the record, since learning how to tie the correct knot (over 10 years ago now), I’ve had no problem with laces that have come with any of the following brands of shoes:
- Nike
- New Balance
- Asics
- Converse
- Vans
>Makes a knot both tidy and tight.
I think I'd find this harder to remember than the principle.
If it landed up perpendicular, start over (i.e. the part before you make the loops) with doing the opposite of what you did before e.g. right-over-left rather than left-over-right.
For me it was very easy to fix the pre-loop stage, trying to change the loop stage seemed way harder to me as I was already so practiced at it.
