FitBit Naked Tracker!

I've just had a flash of brilliance (no pun intended)! I've had my FitBit Flex since last October, and I think it's pretty neat. Besides helping to motivate me to be more active, it's also a sleep timer. You tap on it to tell it when you're going to sleep, and then when you wake up, you tap on it again to tell it, you guess it, you're awake. Now, I have just put 2 and 2 together: I sleep naked anyway, so the FitBit is also more or less a naked timer. The thought just occurred to me that I should start putting it to sleep whenever I'm naked! Then I can keep track of how much time I'm spending naked, and hopefully try to beat my own record!
