(Current year - almost )2010 - (mid 50's)1955 = 55 years + 25 yo
(*assuming* a "young" age at the time of employment in this field) = 80 yo
today . . . . . . . I suppose he could have been 20 yo, or maybe he got in
the field in the early 60's - either scenario only varies the age by 5-10
years . . . . FYI, anything younger than 70 is not elderly !! (The older
you get, the older "old / elderly" gets !!! LOLOL !! One of my nursing
texts labels 60 - 74 as "young-old", 75 - 84 is "middle-old", and >85 is
"old-old". (Fundamentals of Nursing, The Art and Science of Nursing Care,
6th Ed., pg. 450) There are nearly 40 million older Americans today and
that will double by 2030 (just Americans - not counting the world
population), which is why technology needs to be considerate of this
population in their development efforts (KIS). These folks have been
through A LOT of change, more so than probably any other generation ever has
or will. I can only hope to keep up at that age !!
I took my first computer class in the early 80's. They were still teaching
about the earliest computers and tubes at that time . . . . don't know if
they still teach about that today - other than a fleeting mention.
