That's part of why I write so much in the Summer holidays... keeps my mind active! I'm just so happy I never have to do maths class again.

Intelligence is something that comes naturally, but if you don't do anything for months on end, which you won't be doing, then you go dumb... usually quicker the older you get. You don't have to worry about becoming dumb or anything... you're still young and work plenty. You've got a healthy mind!
