How old is Grandma

I transferred to England in 1987 with the Air Force. Met a girl who had her own flat (apartment).

Remember, this is 1987 and the entire apartment building had no central heat or air. Didn't need air most of the time but if you wanted heat, you had to bring your own.
She had two "Calor" (propane) gas heaters we moved from room to room.

And, the apartment electric was on a meter that you had to put coins in to keep your electric on!!!!

I thought I was in a third world country!!!

We married, cause I couldn't resist the accent but divorced 7 years later when she got the 7 year itch.
