D: "We're getting old, mommy"
M: "Really dude, why are we getting old?"
D: "We drink too much."
Me to myself: Really? Where is he going with this? Am I up for whatever it coming?
Me to him: "What are we drinking that is making us old?"
D: "Mommy, we are drinking too much water and that is making us too old. And too much juice too. It's making our legs old".
