Unable to get lives to change when humanoid dies. Any Idea why?

I have been working on the script for a little while and I can get the lives to change but it changes the second the game starts and keeps counting down instead of only by 1 when they die. Any ideas guys. Here is the script for further inspection.

game.Players.PlayerAdded:connect(function(plr)
	local Stats = Instance.new('IntValue', plr)
	Stats.Name = 'leaderstats'
	
	local Lives = Instance.new('IntValue', Stats)
	Lives.Name = 'Lives'
	Lives.Value = 25
	
	local Stage = Instance.new('IntValue', Stats)
	Stage.Name = 'Stage'
	Stage.Value = 1
	
	local Timer = Instance.new('IntValue', Stats)
	Timer.Name = 'Time'
	Timer.Value = 0
	while true do
		wait(1)
		Timer.Value = Timer.Value +1

	if game.Players.LocalPlayer.Character.Humanoid.died 
		then do
		Lives.Value = Lives.Value -1
	end end end end)

Any help would be appreciated. I can't seem to understand why it's not working. I was referencing the wiki but to no luck.

You're formatting this script really weird...

First off, you have too many "ends". There should only be three, not four.

It's because Humanoid.Died is an event, not a property.

game.Players.PlayerAdded:connect(function(plr)
    local Stats = Instance.new('IntValue', plr)
    Stats.Name = 'leaderstats'

    local Lives = Instance.new('IntValue', Stats)
    Lives.Name = 'Lives'
    Lives.Value = 25

    local Stage = Instance.new('IntValue', Stats)
    Stage.Name = 'Stage'
    Stage.Value = 1

    local Timer = Instance.new('IntValue', Stats)
    Timer.Name = 'Time'
    Timer.Value = 0
    while true do
        wait(1)
        Timer.Value = Timer.Value +1
	game.Players.LocalPlayer.Character.Humanoid.Died:Connect(function(plr)
		Lives.Value = Lives.Value -1
	end)
    end 
end)

FYI: in if statement is formatted

if x == x then
	--code
end

You don't need the do after the then.

Died is a event signal like PlayerAdded that fires when (as the name implies) the Player's Character dies. You'd have to :Connect to it like you did with PlayerAdded:

game.Players.PlayerAdded:Connect(function(plr)

-- Never use the 2nd argument for Instance.new(); it's bad performance-wise
    local Stats = Instance.new('IntValue')
    Stats.Name = 'leaderstats'
	Stats.Parent = plr

    local Lives = Instance.new('IntValue')
    Lives.Name = 'Lives'
    Lives.Value = 25
	Lives.Parent = Stats

    local Stage = Instance.new('IntValue')
    Stage.Name = 'Stage'
    Stage.Value = 1
	Stage.Parent = Stats

    local Timer = Instance.new('IntValue')
    Timer.Name = 'Time'
    Timer.Value = 0
	Timer.Parent = Stats

    while true do
        wait(1)
        Timer.Value = Timer.Value +1

-- Died has to be exactly spelt Died, because it's a special ROBLOX thing
    game.Players.LocalPlayer.Character.Humanoid.Died:Connect(function() 
        Lives.Value = Lives.Value -1
	end)

	end
end)
