The One Who Wields the Power of God
I'm not necessarily "equating old age with suffering and death"; of course they're not always the case. I'm just pointing out that at this point in time the number of people who do manage to live their lives healthy enough (or got lucky with the genetic lottery, because after the period of reproduction there's a shadow cast that means that while natural selection may influence up until then, it doesn't optimize or select for anything past reproduction) to live as happy as you do now isn't quite so high. Often they get hit by diseases because their body inevitably breaks down (and often genetics plays a role in healthspans. Not to say that lifestyle doesn't play a part, but even the healthiest of people at this point in time can't control their genes, or at least, not yet) as they age; basically, I'm saying that it might not be the case for you right now (because who knows about the future, but hopefully it all goes alright), but a majority of people in their older years spend a lot of money and time on medications and treatments for things like atherosclerosis and cardiovascular disease, cancer, arthritis, cataracts, osteoporosis, type 2 diabetes, hypertension and Alzheimer's disease. The incidence of all of these diseases increases rapidly with aging, and increases exponentially with age, in the case of cancer (found this off the Wikipedia page for age related diseases).It seems to me, Accelerator, that you are equating old age with suffering and death. Newsflash: Doesn't always occur! My dad is 93 years young and could probably out hike most people; his doc tells him he has a heart of a 60-year-old. Yes, he is slowing down but uses the "downtime" exercising his incredible mind with reading, Scrabble and other activities that stimulate his brain. I am 61 years old and life has never been better; my kids are grown (and doing well), I have a grandson and plenty of time to do what I enjoy. I have never been at a better place in life, and believe me, I've been down some pretty dark roads. As for not wanting people to not have the advantage of this fountain of youth that has yet to be found; of course not, I would take advantage myself for the physical benefits---I'm not totally nuts! But I don't think it's going to happen in my lifetime and if it happens in yours most likely it will be only for the rich and powerful who will be living on the moon for the earth will no longer be as it once was if things continue going the way they are going now.
As for "the random suffering that happens for no reason" I, of course, cannot answer but can only say maybe there is a reason. Yes, I grapple with that one too and it seems so unfair and brutal that suffering exists that could be irradicated if only society would put it's priorities straight, id est, stop wars and use all that money and man/woman power to help those in need! But realistically that is not going to happen.
Also, nice to know you're fine with rejuvenation (as confusing as that might be given that you just said you were against, and I quote, "science interfering"), but I think this article (here: Anxieties over Individual and Societal Stasis are a Displacement Activity) has something that may alleviate your concerns over a rich and powerful elite.
Now, the random suffering that happens for no reason can be attributed to a combination of many factors, and yes much of it wouldn't be a problem if people just got along and weren't such pricks, but that's a problem that can only be addressed if our leaders thought it was a problem worth taking (many do, but often politics comes into play and they change to stay in power). The people can make that change, but it's a bit of a numbers game that also involves politics, so it's quite the complicated problem (too change from the inside; if someone with a huge amount of power decides "hey, let's change all this," then this would be much, much easier, but many in power still want to keep that power, and unless helping people has an incentive then they likely won't do it). It's all frustrating to me too.
