How would I make this script only activate after I use my tool 5 times?

local player = game.Players.LocalPlayer
local character = player.Character
local humanoid = character:FindFirstChild('Humanoid')

script.Parent.Activated:connect(function()
	if humanoid then
		humanoid.Health = humanoid.Health + 0 --
		wait(2)
		script.Parent:remove()
	end
end)

Use a check

local player = game.Players.LocalPlayer
local character = player.Character
local humanoid = character:FindFirstChild('Humanoid')
local Index = 0
local Max = 5

script.Parent.Activated:connect(function()
    if humanoid and Index == Max then 
        humanoid.Health = humanoid.Health + 0 --
        wait(2)
        script.Parent:remove()
    else
	Index = Index + 1
    end
end)
