Is this the most optimal way to create infinite health training dummies?

I used:

local hum = script.Parent:WaitForChild("Humanoid")

hum.HealthChanged:Connect(function()
	hum.Health = hum.MaxHealth
end)

I was just wondering if this is the most optimal way of doing this, however it might have some problems such as if it takes more than its MaxHealth which I can fix by just increasing it to a larger number.

Thanks!
