As far as tech goes, I admit I've gotten lazy about keeping up. First phone "number" was three shorts and two longs. You figure it out. Built my first modem in 1982, transmitted at a blazing speed of 400 bits/minute and was good for about 12 feet. Created a product line in 1987 that was the first PC based application for a specific industrial fire protection problem. Also had two ideas during that process that resulted in US patents. As for "cell phones" my first one was about the size of a small loaf of bread. been on the Apple wagon since the model 3. Still have a functioning ipod. But sorry, no flip phones.
Oh, did have an early blackberry.
