I believe that I doesn't matter when you were born. You could argue that in the 1800s there was no real medicine and that most people died from what is now a silly disease that is treatable with just a pill, but back then Global Warming wasn't an issue and people enjoyed a cleaner environment and greener grass. In the future, humans might be able to live for hundreds or even thousands of years, possibly merging with machines and having virtually no disabilities, discovering space and colonizing knew planets, but we would still have something better than them let it be more humanity, better morals, or who knows what they will look back at and see us better in than them. As an Egyptian, I like to believe that our ancestors built the pyramids as a memorial of their hard work in life and the blessings they achieved and I think that is what truly matters, that we leave something for the generations to come to remember us with otherwise we'll just be forgotten. But what do I know, i'm just another random guy on the internet :)
