Many factors influence these characteristics, such as background, training, attitude, and upbringing. For example, a fun person at 22 can still be fun at 52, and a person can be trustworthy
(or not) for an entire career. Also, if an age group has a certain
characteristic, it may not be the same for every person in that age group. “My mentor was a very gifted fifty-something, while the
other fifty-somethings that I work with tend to be turf-sensitive
and manipulative,” says one respondent (closest to age 42).
