While we were eating dinner with Mr. Callahan, his cell phone rang.  He was still working every day, despite being 95 years old.  He had known about my hobby of collecting antique lancets, and he had put out some inquiries on where I might find some that are in private collections, and this was one of his work associates calling him back.  Mr. Callahan's friend from work, Oscar, has a big source of them.  His grandfather used to work for a medical supply house back in the 1920's, and he has things going back well before that time.  I was getting excited.  I wanted to go right now to  look at the collection.  Tara stopped me.   I had a project due for work tomorrow, so that would be out of the question for tonight, though Mr. Callahan was interested.  He has a lot of energy.  He is 95 years old and is in great shape.  I asked him how he enjoyed his meal, and he really liked it.   He said mostly that he is a vegetarian.   Not because of ideology, but for health, but he does enjoy a good steak now and then.  He laughed, and said it was his only vice.  He rarely drinks, and the women chase him. He laughed.
