Be aware of language and terminology.

Many adults who are technically “senior citizens” resist the idea of being called a “senior citizen”.  Some people, particularly those not born in the U.S.,  don’t identify as “baby boomers” despite the fact that they fall within that age bracket.  For some, the word “volunteer” has a pejorative meaning, especially if they perceive volunteers as not being valued and respected.  Language is a very sensitive topic and it is wise to be aware of words that might offend your target audience.
