Expected Turns To Find a Taller Guy

You pick a random person $X$ on the street and note their height. You then keep picking people at random (independently, from the same population) until you find someone taller than $X$. Let $N$ be the number of people you pick after $X$ up to and including the first taller person. Assume heights have a continuous distribution, so there are no ties. What is $E[N]$? (Enter Infinity if it diverges.)
