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)
