Clicking mechanic stopping after death?

Basiclly this script makes you faster every time you click

I Was just messing around and i noticed that when you die the starterplayerscript stops working:

local Players = game:GetService("Players")
local player = Players.LocalPlayer
local char = player.CharacterAdded:Wait()
local mouse = player:GetMouse()
local Cam = game.Workspace.CurrentCamera
mouse.Button1Up:Connect(function()
    char.Humanoid.WalkSpeed += 0.5
    end)
