Should we Cure Aging?

Aging is a part of life, and I think everyone should just accept that it's gonna happen no matter what, and aging leads to death, and dying is natures way of making room for other people. If we stopped aging, the world would quickly become overpopulated since people wouldn't die, but more people would get born. It would end with chaos.
 
But if we could settle other planets then we could put the immortals on other planets.
 
I don't see how aging will ever be cured. We're obviously not ever going to live forever. But I don't see a problem with living longer. We're already doing that since our lifetimes were much shorter back in the day.
