I think the first SDMBCDP was less than 20 years ago, so you could not have gotten points for him that long ago. Sadly.
This was my inaugural Death Pool, and the only points I got were for Henry Aaron.
I’d gladly give them back, if I could.
You’re right that infinity isn’t a number. But the rest of that is a bit off. “Countably infinite” (IOW, the cardinality of the set of counting numbers, i.e. the positive integers) is greater than the cardinality of any specific counting number. Not both greater than and less than and equal to, just greater than.
I know I was being casual, mathematically, in referring to ‘infinity’ in the manner I did, but c’mon. The cardinality of {2,4,6,8,10,…} is the same as the cardinality of {1,2,3,4,5,…} despite the former’s lack of any odd numbers. And toss the first seven odd numbers into that first set, and the cardinality is unchanged.
Or from a non-mathematician’s perspective, infinity/2 + 7 = infinity. Sheesh.
I’d have been happier if you’d gotten thirty more points for him by having him in a Death Pool thirty years ago, and getting the points for him back then. 
To make a comparison that is in line with the Death Pool, consider the case of Steve Allen, who gave it up in double-aught at 22 points. For the intervening 15 year period prior to the exit of Jayne Meadows, his widow, who gave up 5 points, was he then older than her (bearing in mind that she was initially born before him)? I am saying that the practical age of a non-living person is not a meaningful value with respect to the points-age of a living person. “Infinity” is not greater than any value because it is not meaningful relative to any value. The number of real values between any arbitrary x and any arbitrary y is either infinite or zero (when x = y), so the only number that infinity has any meaningful relationship to is zero (and not the approximate form of 0.00000…1 but the genuine logical zero).
But, this bit of quibbling does not really belong in the dying 2021 CDP (which is currently worth 8284 points until the next person posts in it).
Look, if you’re going to mix infinities with different cardinalities as if they were all the same, then stop pretending to know stuff you don’t.
Yes, that was the joke I was making.
So now I’ve won the Opening Kickoff Award (Carol Channing, 2019, all by myself), and the Final Hours Award, this year, with these losers fine folks.
Sweet 16 with 69 points. I’ll take it. 
Although at age 16, I had no idea that the number 69 had any meaning other than being after 68 and before 70. LOL.
