Suggestion for next update

Dear Mojang (Cave game creater/Minecraft)

Um I would like to send you a suggestion for minecraft. Well you should add a thirst bar so you can die out of thirst but it runs out slower than the hunger bar. This would make the game harder and more challenging as the bar would run out quicker in the nether dimension and the end dimension. The thirst bar is a good idea but for that to happen you have to mine sand and craft glass bottles to drink out of so it becomes a vital part of the game
