There's one day in the week that makes you groan with annoyance and a touch of despair. It's the one day you can't get used to, no matter how often it comes rolling around and no matter how often you've tried to set your mind to dealing with it. For you, that day is probably Monday. For your liver, it's Friday. Every week when Friday rolls around, your liver braces for an onslaught of pain. So take it easy on your liver when the weekend's over, and remember that a bad Monday morning is your liver's payback for your weekend. Wear this tee or hoodie as a reminder.
