hmm? strange i opened my paypal account when i was 16 and never had a problem since, and my ebay account was opened when i was 15 but i lied about my age on that one, i later went back and corrected it when i came of age, but i never had a problem with the age for either accounts, i don't think you have to worry about much, if worst comes to worst just say you made a mistake, no harm no foul
