Seems that some scientists are starting to think this way too. How about this quote "For many scientists who know about such things, the question isn’t whether the first person to live forever has been born, but how old they are."
Supposedly those of us that make it another 20-30 years can expect to make it to 125. And, in those 20-30 years we will probably discover things that will make it possible to go even longer - presumably indefinitely. The kicker for many (like smokers - you know who I'm talking to!!) will be to make it the next 20-30 years.
The enzyme discussed in the linked article isn't considered the final solution, and is considered to be a weak attempt - but notably it is the very first product that attempts to slow down or reverse ageing (not expected to be successful in the latter). Note that this is a measure of how long a cell can divide without dying - possibly not what you are thinking of when you think of reversing ageing. :-)
Also posed in the article - current population predictions don't take into account current population not dying. As Stephen Hawking has said, our species will need to get off this planet if we are to continue. If we aren't dying then the only way to stop the population explosion will be to stop having babies - I can't see that as a viable option either. We will need somewhere else to put people!
