I honestly don’t think that people will be able to pass 120 years. Sure, you’ll get exceptions that go a couple of years over that but at that age, a wrong sneeze might rupture something.
From a health perspective, everybody goes on about how healthy people are eating these days, but science don’t even always know what is considered healthy. Between all the junk they inject the animals we eat to the genetically modified foods and even poor quality of drinking water, you pretty much have to go organic all the way as there is no way to know what the long term effects of some of those things are. Then on top of that, you get diets like Banting which goes completely against everything that “science” today teaches. I visit a relatively up-to-date dietitian once a year who isn’t very impressed with Banting, but yet on “Banting” so far, I’ve lost about 6kg and dropped my LDL cholesterol by 1 point in a couple of months without exercise and a lot of cheating (hence the quotes).
From a medical perspective, there are thousands of diseases and cancers that we’re not even close to a cure for. Besides that, people are dying from things we know a lot about. We know more about the heart than we’ve ever known before, have done heart transplants, you name it… yet more people are dying of heart related issues than ever before.
From a global perspective, I think humans in general are pretty selfish and will most probably end up destroying ourselves and the planet in maybe the next 50 years. My feeling is that tensions all over the world is rising and it is building up to something bad and combine that with people voting for populist idiots to run the various countries… sounds like a great recipe for disaster. Besides that, companies would do something that is hazardous to the environment and people, just for the sake of making money. So if a war, crime or terrorists doesn’t get us, global warming probably will.
From a Christian perspective, there is actually a reason why the “maximum” age was reduced to 120 years. If you combine that with the viewpoint that being human is just a temporary point in time to something better anyway, then aging isn’t so bad.
I’m personally fine with aging (and eventually dying). It is good to let old ideas / perspectives die to make place for new and better ones. Also knowing that there is a limit is motivation for living the one life you have to the fullest. Heck, even with the age limit you see people all over just in a state of existence and not living.
Also as mentioned in other posts, the world isn’t really geared for old people all of a sudden not dying.
I am however not opposed to living longer. I just don’t think we’ll really break past the 120 limit.
