It was a Pathfinder Campaign we had been playing for a while, and our group consisted of 4 humans men, a fighter, a ranger, a rogue, and a wizard. We were missing a healer, but had some hopes for that when we got a 5th player to join along.
Unfortunately they were a newcomer who got upset that instead of 'living forever' the elves were just 'very long lived' and even there he whined because dragons could 'easily outlive them'.
It got to a point that after 3 play sessions the group was sick and tired of his whining and asked him to behave. Instead, he tried to whine about giving him some means of immortality in game..
I personally kind-of emphasized a bit because I like to try and pursue some form "eternal youth" variety of immortality, because this particular GM had run our games in succession with later games being hundreds of years after our previous ones and letting us see how the world changed from the actions of the previous heroes. Mostly we played humans because our group just had that preference, and it fit.
I played one round as a Monk who reached 20th level and thus, became 'immortal' and a quest-giving NPC for later heroes, someone who was set as a guardian of a potent relic containing a previous "big bad" the heroes couldn't vanquish, but managed to seal away.
The elf guy was irritating because of the player more than the race-pick, but after that, I dislike Elves to some point due to association with the whiner.
