Early-set Alzheimer's

To truly get the irony, bear in mind that I consume a couple of times my own mass in Diet Coke every week...

Me: "I think we should stop cooking with aluminum foil"
The bride: "Why's that?"
Me: "I hear aluminum consumption might be linked to Alzheimer's."
The bride. "Uh-huh. What's that in your hand?"
Me: "Eh?"
The bride: "Your hand. What are you drinking?"
Me: "Oh.. er... this Diet Coke... in an aluminum can... "
The bride: "..."
Me: "I suppose the aluminum foil can stay..."
The bride: "Yeah. Sounds good."
