Okay -- it's another rant. Last week at a UCLA panel I was on, an exasperated audience member asked for a definition of 'senior', annoyed at what sounded like stereotypical patronizing about technology use. I stupidly responded that it was a census definition of age 65+. Actually the census categorizes percentages multiple ways: 60-plus, 62-plus, 65-plus, and 75-plus. Wish everyone did that. Sixty-five is the year of Medicare eligibility, it was once the year for pensions and mandatory retirement and for many it is the year of full Social Security eligibility. It has been used as a political demographic, synonymous with 'seniors' as in the example of the $250 stimulus check to seniors.
