local Players = game:GetService("Players")

local Component_Health:{[Player]:number}={}


local function PlayerAdded(Plr:Player):()
	Component_Health[Plr]=100
	Plr.CharacterAdded:Connect(function(char):()
		local humanoid = char:WaitForChild("Humanoid") :: Humanoid
		Component_Health[Plr]=humanoid.Health
	end)
end

Players.PlayerRemoving:Connect(function(plr):()
	Component_Health[plr]=nil
end)

Players.PlayerAdded:Connect(PlayerAdded)
for i,v in Players:GetPlayers() do PlayerAdded(v) end

that is NOT more efficient than just doing humanoid.Health what are you on
