Thanks, guys! I appreciate the sentiment.
Every milestone adds up. When you are little, you want the presents, after 21 you don't have much else to "need" and by middle age you are pretty indifferent to it.
At some point, you have to accept that you are certainly in the 2nd half of your life, not the first, and it changes you.
When friends and family of about your own age start dying, then you really start appreciating each additional year.
And when they begin starting with "6" (or >6 OMG) then you have to be grateful for each one.
Good luck to you all!
