Add regen to this humanoid script?

I have been trying at it all night to add a regen to this script's humanoid when it dies or gets parented to nil. Here is the source:

function waitForChild(parent, childName)
	local child = parent:findFirstChild(childName)
	if child then return child end
	while true do
		child = parent.ChildAdded:wait()
		if child.Name==childName then return child end
	end
end

local function weldBetween(a, b)
    local weld = Instance.new("Motor6D")
    weld.Part0 = a
    weld.Part1 = b
    weld.C0 = CFrame.new()
    weld.C1 = b.CFrame:inverse()*a.CFrame
    weld.Parent = a
    return weld;
end

local function jointBetween(a, b, cfa, cfb)
    local weld = Instance.new("Motor6D")
    weld.Part0 = a
    weld.Part1 = b
    weld.C0 = cfa
    weld.C1 = cfb
    weld.Parent = a
    return weld;
end

	local parent = workspace:FindFirstChild("Dummy")
	if (parent == nil) then
		print("making dummy")
		parent = Instance.new("Model", game.Workspace)
		parent.Name = "SuperNoob"		
	end

	for index, child in pairs(parent:GetChildren()) do
		if (child.Name ~= "AnimSaves") then
			child:Destroy()
		end
	end

I need someone to modify this so the humanoid safely regens when died, without breaking the functions. Can someone attempt this for me?
