Do games like that even exist?
Also, chaoticag, pretty much anything can increase your risk of cancer of some kind. Cancer is like that.
Yes, but some things do that more so than others.
I don't like the idea of immortality, to be honest. Think: there will of course be limits to how far we can go with rejuvination. Now imagine that we have the low birth rate/low death rate, and then some disaster strikes. It doesn't matter what. But it drastically reduces the population. Then we have a bunch of people who are used to a very, very low birth rate. It could be difficult to re grow the lost population, unless you forced people to have kids (which realistically you can't do).
Then of course, with such a low birth rate, there will be a vast number of people much, much older than the few young children. These young children would probably never be able to interact very well with any one else because either they don't get enough contact with kids their own age (and therefore don't develop good communication skills), or they are in such small groups that they basically form tiny cliques. Cliques, as a rule, are a bad thing. They cause division and distrust. I don't want humanity to become a collection of dozens of little cliques that can't accept each other.
That guy had a good argument, Armok, but I have to disagree with him.
Though I'm all for new medical treatments that might allow more people to have the same chances at life as everyone else.
