How much cum have you swallowed?

I'm an old man, 81.I've been been sucking cocks since I was 12.Been swallowing cum since I was 13,so that's alot of cocks and cum. The reason I bring this up, the other day I was sitting on the porch sipping a bit of rum and puffing on a cigar and was thinking about duing a ancestral search. Get a DNA test see what my roots were.
then I started thinking about how would cum effect your DNA. I mean with every thing we swallow our body absorbs nutrients, right?
So I started to think about all those cocks I sucked. Things got scary.
I calculated that in the last 68+ years I sucked roughly 750-850 different cocks, long ones, short ones, skinny ones and my favorite, thick ones. Of course alot of those were one time but the majority were multiple times. Now being a cum lover I swallowed copious quantities of that delicious fluid. Then you add me cleaning up after other guys that adds to the total.
Let's be conservative and say the average amount was one and a half ozs times the number of times I sucked and cleaned up.
Let's do the math.I going to average things out. I probably sucked cock close to get ready,8000 times!No wonder my jaw is sore. 8000 times 1 3/4 ozs is 14000 ozs or440 quarts or that's about 110 gallons.
HOLY CRAP !!!!! I'M A CUM SLUT!
This has to effect your DNA .
Do you have any thoughts on this?
I need to get a hobby other than sucking cock.
