Before?? and after

Where do 'before' pictures suddenly pop out from? 'Oh, my acne looks particularly bad today, where's the camera?' 'Look how far my gut hangs over my belt, I think I'll take my shirt off, frown, and document it. ' 'This may be a new record of plaque on my teeth, click' It worries me. Should I start taking random pictures of myself in odd poses in case my body suddenly gets in shape? Should I stop brushing for a few months and then contact Crest to see if they need a testimonial? I guess I'll just take some regular photos and see if I can change anything in the future.
