But when we are living in the thick of it we live much more within each other and the greater whole of society because we have to. That's how we survive. We give up some of our brainspace to ideas and systems that are built communally, both on a local/familial level and on an entire social level.
In other words, we spend a lot of our time going with the flow and allowing our opinions to be shaped by those we trust or love. Or at least I think that's part of it.
Edit: And in that sense we see individuals dying, but as we live we don't necessarily ponder ourselves dying as an individual because much of what we do and care about on a day to day basis will outlive us e.g. our families and ideals.
