There are several examples of Miqo'te purring in dialogue. Some do, some don't. In regards to "hissing" Miqo'te Naming Conventions mentions a harsh aitch sound found commonly in names that comes from the ancient Miqo'te language that other races are apparently unable to pronounce/replicate.

The old racial lore should help answer these questions:

According to the Las Vegas Lore Panel, all Eorzean races have a similar lifespan to real world humans, with the exception of Elezen living a little bit longer and having a slightly prolonged development stage. So biologically, Miqo'te can live to be 100~120 years old, however, because Eorzea is a harsh environment with war, plague, poor healthcare, and hygiene most Eorzeans have a significantly lower life expectancy of only 30-50 years.
Here's the quote from Fernehalwes:
Q: What are the age scales of every race? How long do they live and how long does it take them to become an adult?
Fernehalwes: Okay, yeah I asked about this and I was told that age-scale wise the five races biologically have the same lifespan as we do here on earth. They can live one hundred, one hundred and twenty biologically. The thing is, here we have modern medicine, we have jobs that don't take us on to the battlefield, we have food in refrigerators not sitting in a barrel. And so we can live that long, whereas, in Eorzea its a much harsher realm. I wouldn't expect most people would live longer than like thirty years. That's the thing, so you get an average lifespan that is a lot shorter, y'know in the forties, fifties.
That said, Elezen actually do have a longer lifespan than the other four races. And this also appears when they go from child to puberty to adulthood. So which is why you'll see in 1.0 there was a bunch of Elezen children that appeared in some of the quests and they appear again in 2.0, and they're still children. And you think well it's been five years why are they still children? It's because again that childhood for Elezen can last much longer. And they end up living longer as well. Um, but for the most part it's pretty much just the same as us, but with more... fatality.
