Grandpa and Grandma were six years apart in their age. Today would've been Grandpa's birthday, and had he lived, which he didn't, he would've been 113 today.
But on this blog, Grandma is perpetually 104. She doesn't age, much like what you see in the Peanuts comic strip or the Family Circus. The kids in the Family Circus have birthdays and Christmas every year but they stay the same year to year.
So since Grandma is always 104 and Grandpa was six years older, that means he has to be 110 (he would've been if he had lived. But he died in 1978, so obviously he's now deceased.)
I believe on his birthday last year I mentioned how old he was (or would've been), which was 112. So now that he's been downgraded to a permanent 110, he's younger this year than he was last! The ravages of time are very terrible.
But at least here, from now on, every time it's his birthday he will still be 110.
Happy 110th birthday again, Grandpa!
UPDATE: Amazon.com sells 100th birthday supplies but not for the 110th. So if there's any enterprising entrepreneurs out there, there's a niche market for you to exploit. I keep hearing that with modern medicine and the various modern procedures living to a ripe old age -- which I would define as anything over 109 -- is going to be more and more common. So maybe by this time a 100 years from now, Amazon will be selling 200th birthday supplies. Of course they'll have to update everything. The "over the hill" stuff will be moved from the 50th birthday to the 90th. And so forth. By then 50 will be the new 15. A guy like me, in my upper 50s, will no longer be a broken down wreck. It'll be a beautiful new age, living longer and spending your children's inheritance in more profligate ways.
