I tried doing things like that and found it unnecessarily risky, particularly when an Aeropress avoids the problem entirely.
To be fair, you can make a big mess with the Aeropress while you push down on the plunger, so maybe I shouldn’t praise its safety either.
That is an euphemism for “don’t eat anything yummy”.
It may or may not extend your life, but it will make it feel unbearably long.
