Does Peeing Clear Really Mean You're Hydrated?

Every time I visit the locker room of a pro sports team I make sure I visit the restrooms.Often, I’m genuinely answering the call of nature. But even if I don’t really need to pee, I’ll usually make an excuse to go and take a quick look out of professional interest.Now, I know that sounds a bit weird, but hear me out. What I tend to look for is an ‘Armstrong Chart’ pasted up on the wall above the facilities.Armstrong Charts look a bit like a paint color swatch you’d find in any hardware store. They show a range of eight hues, gradually transitioning from off-white through various shades of yellow to finish on a nasty greenish-looking brown.These charts can be found in nearly all bathrooms in elite sports facilities. I’ve spotted them in the toilets of just about every single NBA, NFL, MLB, NHL, NCAA College, Premier League soccer and rugby team that I’ve visited over the past 10 years.
