This datapack limits the lifespan of all entities excluding players in your world to just a minute
So you should not place armor stands or leave your trident on a block or even shooting arrows and leaving them there

This datapack relies on scoreboards , every entity excluding players score gets added by 1 every tick , when their score is 1200 or above , they get killed , a minute is 60 seconds , every second is 20 ticks in minecraft , 20 times 60 is 1200 so that's their lifespan.

How to install :
1.Download the datapack
2.Open the archive
3.Move the folder named : "1 Minute Entity Lifespan" in to the datapacks folder
4.Open the world but if you were already in the world , Run "/reload"
You are now finished
