How To Make The Default Max Health The New Maximum On Game Join?

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

    local Endurance = plr:WaitForChild("leaderstats").Endurance

    local Character = plr.Character or plr.CharacterAdded:wait()

    Character.Humanoid.MaxHealth = 100 + Endurance.Value
    Character.Humanoid.Health = 100 + Endurance.Value
    Endurance.Changed:Connect(function()
        local Character = plr.Character or plr.CharacterAdded:wait()

        Character.Humanoid.MaxHealth = 100 + Endurance.Value
    end)
end)

So This Script Does Work Correctly, It Does Scale My Endurance Value With My Health, But Instead On Game Join It Starts With The Old Default Maximum Instead Of The New One, So Then The Players Health Is Really Low, Can Anyone Fix This?
