I'm dying pretty recently in Minecraft, and I always have fear that my items will go to waste. I found out at this question that you're able to last with your items 5 minutes before they go away. Five minutes!! That's not a lot, so I want to know if it's possible to extend the amount of time you have, and if it is possible, what are all the ways you can do so?
Note that I don't want any command blocks, and I'm playing in a Survival world.
