You are not old enough for Medicare. You are not old enough for regular old social security.
Let me rephrase this...you were NOT born in the FIRST HALF OF THE LAST CENTURY...during the TRUMAN ADMINISTRATION! THAT is old.
So are people who remember telephone "party lines," cars that didn't have any kind of seat belts, plastic crap that was blue (like the sky) on the top and green (like the grass) on the bottom, that some people bought to put over their TV screens to create that new-fangled "color tv." You might be old if you ever worked for fifty-cents an hour, and growing up never saw a pregnant waitress or school teacher (they had to quit when they started showing) or when if you wanted to drive you had to master the stick shift.
