I am trying to make a custom death, but keeping them from death seems to not work?

The goal is to have a script that keeps you from doing the classic roblox OOF that reloads your character. The rest is handled by another script, but it would seem that if something does enough damage you will fully die anyway, why is this?

repeat wait(2) until game.Loaded
game.Players.PlayerAdded:Connect(function(Player)
	local Char = workspace:FindFirstChild(Player.Name)
	while true do
		wait()
		Char.Humanoid.HealthChanged:Connect(function()
			if Char.Humanoid.Health <= 2 then
				Char.Humanoid.Health = Char.Humanoid.MaxHealth
			end
		end)
	end
end)

If you have a custom health system, try this:

local Players = game:GetService("Players")
local function onCharacterAdded(char)
    char:WaitForChild("Humanoid").HealthChanged:Connect(function()
         char.Humanoid.Health = char.Humanoid.MaxHealth -- every time health is changed, set it to maxx
    end)
end
Players.PlayerAdded:Connect(function(p) p.CharacterAdded:Connect(onCharacterAdded) end)

If this helps, please mark as a solution. Metatable out!
