Hmm ok... then for my opinions I will see about that.... but I want to know what do all of you... think......?
Will it be a blessing? Since people marry late... blah
Or a curse? You provoke the ire of others...
Again, this has a lot to do with what type of setting you're putting your characters into. Is this social environment so volatile that a longer lifespan would be seen as a curse - due to the fact that the individual would have to endure the pain and turmoil of every day life for much longer than the average Joe? Or is daily life euphoric and abundant with earthly pleasures, where a longer lifespan would be the envy of others?
Would either of the above create a conflict that is necessary to the story you're trying to tell? Is it integral to the theme you're trying to convey? Does this idea play a large role in your story or is it simply a world building detail that may or may not have some manner of emphasis within your work?
What you're doing, and what we all do at some point, is asking questions you should be asking yourself. It's difficult for us to help you through this process, as we don't know all the - pardon the cliche - gory details.
Writing involves asking yourself questions, trying to answer them, and then asking more. In order for a reader to believe in your world, however far-fetched the setting and concepts may be, you need to have asked yourself all the questions you can think of, even if it's of little importance to the story -
(While carnivorous, snaggle-toothed kumquats aren't very important overall, their juice, when extracted with the proper tool - a low resistance corkscrew with a teakwood handle sanded and finished in very specific low-grav environments - on the third month of the sixteenth season, during your planet's closest pass of its second sun, is the very liquid that cures the disease inherent in very Bablicon Bantha-eater at birth. Their lifespans being a mere two years prior to this discovery, have now exceeded ten. Your planetary famine has been overcome, its economy boosted, and Bablicon Bantha-eating farmers everywhere rejoice in the foresight they had many years previous, when they all - sitting around a campfire, drunk on the King's whiskey - mused about how life was so ironic that the cure to their problems was more than likely effused in the very spirits they were consuming - which, coincidentally, was made with the juicy extract of carnivorous, snaggle-toothed kumquats. Of course, they were referring to the age old habit of drowning in your sorrows, though in hindsight they believed themselves to be the untapped genius of the cosmos. As a result, many Bablicon Bantha-eating farmers then went on try and invent and theorize beyond their simple-minded capabilities, leaving their farms unattended and their herds neglected. Which, in a rare - though not completely unpredictable - twist of fate, led to the deaths of three-quarters of the population of Bablicon Bantha-eaters. Thus, the Planet of Redixulous was sent hurtling back into famine and economical decline, which in turn led to the suicides of many once newly-wealthy, now newly impoverished Bablicon Bantha-eating investors - who, quite literally, had put their money where there mouth was. This, while seemingly irrelevant, led to the adage adopted by intergalactic farmers everywhere: Don't forget to count your Bablicons after you've had a very good idea!).
Asking yourself questions builds depth and helps you to better understand your own work. While we may not be privy to the details, you very well should be. Try to ask all the questions you need to get past the hump in your story (and by no means am I implying you stop asking us - while that may well be what it sounds like, I'm only trying to encourage you to come up with your own solution, since you know your story better than we do).
