> This work is risky, but the risk is comparable to doing your own car repairs, or climbing on the roof of your house to clean your gutters.

I wonder what the net impact of an article like this is:

* How much money is saved by garage door owners?

* How much money is lost by professionals?

* How many people are injured/killed because this article made them think this was doable at acceptable risk, when they otherwise wouldn't have attempted it?

* How many people would've attempted it anyway, and would've been injured, but this article helped them not to be injured?

Modern bonus:

* How many people are injured because a YouTube/TikTok/etc. DIY influencer is informed by this article, makes a YouTube video that muddies the information, and people are inspired by the influencer video to attempt it?
