How to run a while true loop after the condition changes?

The following script only prints twice. I believe this is because once the condition is no longer met the loop no longer runs even when the condition is correct again.

x = false

while x == false do
	print("x is false")
	wait(1)
	x = true
end

while x == true do
	print("x is true")
	wait(1)
	x = false
end

My question is what would be the solution to make this go on forever? (as in printing x = true then x = false repeatedly instead of just once.)

The application which I am using it for is a game loop, but this shows the issue I am facing on a smaller scale.
