[Solved] Trying to understand coroutine

I've been trying to learn how coroutine work, but with not much success. Below is my testing code, what have I done wrong?

function one()
  while true do
	print("one")
	sleep(1)
	print("two")
	sleep(1)
  end
end

function two()
  while true do
	print("three")
	sleep(1)
	print("four")
	sleep(1)
  end
end

o = coroutine.create(one)
co = coroutine.create(two)

while true do
  coroutine.resume(o)
  coroutine.resume(co)
end

--print(coroutine.status(co))
print("\nThe end.")

The thing is the infinite loop. You cannot resume a coroutine wich is dead. If you dont know the term coroutine and death together, you should read this tutorial by Bubba.

Thank you for passing me that, it has helped immensely!
