A few things ... First, I'm not worried much about the integration of memory and experience of an extra 50-100 years of life into ones day to day life. If you compare the nuance and complexity of daily urban life in 2014 to, say, daily peasant life in the 15th century, it's a much, much more dramatic enlargement of "scope" than simply adding more years of current experience. I think we have every reason to suspect people will handle it just fine. What we should worry about, or at least own up to, is that an extra 50-100 years of life is about as revolutionary to us as our current health and food security is to those 15th century peasants. Which is to say, a 15th century peasant could have had the same fantastical questions about "what in the world will people do when they have all the food they could ever want and never go hungry?". And as we know, the answer is that most of them will just slowly eat themselves to death in front of the (tv or tv equivalent). So perhaps we can extrapolate from there ... some small number will experience a golden age of speaking italian and learning to play harpsichord, but most will be bloated and stationary with a VR headset on.
