Rich, I did think of these truffles for your birthday until I read some of the cautions. Here are a few that cause me to consider alternatives for you.
"Senior citizens should use caution after consuming cocoa when riding as a passenger in a vehicle one formerly operated, operating arthritic joints, or performing other senior-citizen activities such as outdoor shuffle-boarding or bridge. Cocoa will cause drowsiness in addition to normal senior drowsiness. Cocoa should be taken only in the company of a defibrillator-equipped trained paramedic. Cocoa may affect you within minutes of consumption. In order to offset this possibility, the senior consumer should be wearing Depends (R of Kimberly-Clark, Inc.) or equivalent."
