Help with hunger system

[Bkkpro1980 (LocalPlayer)]

You can write your topic however you want, but you need to answer these questions:

1. What do you want to achieve? Just a hunger system or smth

2. What is the issue? The number value wont change (no errors popping up on the console)

3. What solutions have you tried so far? i tried changing some variables

game.Players.PlayerAdded:Connect(function(plr)
	local char = plr.Character or plr.CharacterAdded:Wait()
	local hunger:NumberValue = plr:WaitForChild("Hunger")
	while task.wait(1) do
		if hunger.Value >= .1 then
			hunger.Value -= .1
		else
			char:WaitForChild("Humanoid").Health -= 5
		end
	end

	plr.CharacterAdded:Connect(function(chr)
		hunger.Value = 100
	end)
end)

HERES THE FIX

game.Players.PlayerAdded:Connect(function(plr)
	plr.CharacterAdded:Connect(function(char)
		local hunger : NumberValue = plr:WaitForChild("Hunger")
		while task.wait(1) do
			if hunger.Value > 0 then
				hunger.Value -= .1
			else -- if it is 0 then DAMAGE! 
				char:WaitForChild("Humanoid").Health -= 5
			end
		end

		hunger.Value = 100
	end)
end)
