Save a players health and give upon return?

so as the question says i would like the game to save the players health and give it to them on return which obviously means its datastore time (yes i will convert to datastore2 later) but with this script i made it says humanoid is not a nil value (line 21)and before i added workspace.name to line 20 it wouldnt say anything at all

script:

local Data = game:GetService("DataStoreService"):GetDataStore("Health")
game.Players.PlayerAdded:Connect(function(plr)
	local Folder = Instance.new("Folder")
	Folder.Name = "Health"
	Folder.Parent = plr
	local Health = Instance.new("IntValue")
	Health.Name = "Health"
	Health.Parent = Folder
print("Gave "..plr.Name.." Health Data")

	local SavedItems = Data:GetAsync(plr.UserId)
	if SavedItems then
		Health.Value = SavedItems.Health
		print(plr.Name.." had Health Data")
	else
		Health.Value = 100
		print(plr.Name.." didn't have Health Data")
	end
	local name = plr.Name
	local Character = workspace.name or plr.Character or plr.CharacterAdded:Wait()
	Character.Humanoid.Health = Health.Value
	Health.Changed:Connect(function()
	Character.Humanoid.Health = Health.Value
	Character.Humanoid.Changed:Connect(function()
		Health = plr.Character.Humanoid.Health
		end)
	end)
end)

game.Players.PlayerRemoving:Connect(function(plr)
	local Saving = {["Health"] = (plr.Health).Health.Value;
		}
	Data:SetAsync(plr.UserId, Saving)
	print("Saved "..plr.Name.."'s Health Data")
end)
