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

    local target = findNearestTorso(parent:WaitForChild('Torso').Position)
    if target ~= nil then
        parent.Humanoid:MoveTo(target.Position, target)
    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?
