The 2nd World war ended in 1945. All the convenience stuff and fast food etc. started gradually after that war. We are talking 66 years since that war. a little later came the better appliances including TV. After the Viet Nam war came the drugs. Then the high tech explosion with emphasis on entertainment which continues today. If anyone can improve on this - please do. I think it is a good basis for figuring out how old grandma should be. Fifty nine is cutting it close.
