You should do a daily series (with the same white or grey card), then you'd know also if you are getting tanned!
I am always tanned. I live in SW Florida with a lot of other Q-tips.
In case others from different areas have never heard the expression; a Q-tip in Florida denotes an old person driving his car (usually a large comfortable one), and because of the slouch and shrinkage, you only see the steering wheel and this white head behind it.
Hence, a Q-tip.
Although I am well over 6 ft tall, I think I am joining the splinter group called the tongue depressors.
