Yes, I do remember the almost predictive devices of the Star Trek series.
To me being a senior citizen means tha you are able to qualify for Social Securiy Benefits and Medicare 65. It's still quite sometime away for me, and by the time I get their I think the programs be something different. It is confusing though especially sine if you want to live for in a senior community then it's 55 for the most part. AARP tells you you qualify for their stuff at 50. Go figure.
