62 is just about the right age to start learning.
Any age is just about the right age.
Very small three octave lap harps are great for travelling, but can be frustrating, especially to a learner, because of the limited range, since arrangements can fall off the end of the harp. There are a lot of harp related pages on the World Wide Web. Have a look at some of them. The Harp mailing list is a great source of information. Don't be afraid to ask pleny of questions.
