Because it seems to not be common knowledge on this thread: JSONB is a format offered by Postgres for a while now, and is recommended over plain JSON primarily for improved read performance.

One of my favorite learnings in school was about the "Endurance limit".
Some materials, like aluminum, will eventually fail under cyclic loading even at tiny, tiny loads. This was a big problem when they built the first passenger jets. Other materials, like steel, have a threshold at which they can be cycled indefinitely without issue.
For something like a pacemaker, I like to imagine they dialed the materials and forces to be within such a threshold so you can keep on ticking!
