I really don’t have a clue, but calculating averages might yield results which don’t represent a directly applicable value. If some people lose tens of years due to dramatic complications, it could weigh up a lot for people who barely lose any life length.
Again, I’m just guessing wildly, but anything which scares people away from smoking is good in my opinion.
I just don’t get why Disney would go to that extent when the lawsuit should have easily been disregarded as not applicable to them. Digging up an old Disney+ membership to find some terms which could apply seems like a terrible PR move for their service.
