This reminds me of "milestones in one's life"...
0 - you're born
5 - you enter school
10 - your first double digit birthday
13 - you're a teenager
16 - you can get your license
18 - you're an "adult"
21 - you're legal on all accounts
55 - you can live in a childless community
65 - you're a senior citiz...
...wait a minute...
...why is there a gap of 34 years where we have zero milestones???
no wonder so many people have a midlife crisis...the only thing they
have that defines them is that Corvette they just bought, and that
isn't automatic like the rest of them!! Well, except the transmission!
