This is interesting because you can't prove you prevented something from happening. It never happened after all. Hank Green has an interesting video on preventative measures are often unsung, because how do you know?

Kids in Africa who would have otherwise died from measles, but didn't get measles in the first place because some people decided to fund and make vaccines and thousands of unnamed and unrecognized volunteers helped distribute and administer these vaccines...

These kids are alive and they don't even know that they wouldn't be alive if it weren't for some people they may never meet, and whose names they'll never know.

Also tangentially, reminds me of an excerpt of a book called The Trigger Effect I read as a kid, which said something along the lines of, when you use your car's brakes to prevent an accident, your life depends on whoever assembled the brakes and quality controlled them. You'll never know their name, and they'll never know that they saved your life.
