DatapacksJava
YAHHS
I don't know my version or loader
Open the Minecraft launcher and look at the profile you play on — it names both, like fabric-loader-1.21.4. The version also shows in the bottom-right corner of the game's main menu.
No loader in the profile name? Then it's plain Minecraft, and these mods won't run — you need Fabric or NeoForge installed first.
Another health system
It's a small datapack that changes the player's life constantly
Every 5 deaths you have you will lose 1 health point (½ heart)
But if you eat a Recovery Heart, you will recover 1 health point up to your max health! (10 Hearts in v1 / 12 hearts in v2)
To change the base life use the next command (values must be between 1-24) and /reload
/scoreboard players set <target> PdV <value>
