For the Record. . .I was joking at Sabo10 and FB about the 'thread jackers' bit. Yes, it was moving off topic, and I was agreeing with Satchel that the discussion should have been about Longevity. . . It was meant as a joke and went out of proportion. For that I'm sorry.
I want to know where the h*ll that other guy came from? I've been rereading this thread, and it came out of no where. Weird. Maybe the dialogue in question was erased by a mod.
In any event, back to topic, I've gotten Longevity, and used it solely for culture, nothing else. By the time I get it I try to have my pop 'balanced' so that the city is at zero growth.
But come to think of it, my other (newer) cities do expand a lot faster. You have to be careful with the growth, as if you don't get an aquaduct and hospital in there asap the growth will styme (Sp?) and I really don't like that.
