I wonder why most of us find senior people lovely and charming. Is it because to love grandpa and granny is vital to our survival as a species, in the same way as we love babies? If so, it would mean that we are either aging slower with time, or being selected somehow to love senior people despite their physical appearance, while they are aging at the same rate but living longer.
Let's say every common characteristic among individuals of the same specie is product of evolution. Many caracteristics are passed by the individuals to their offspring, but only those that were advantageous in some way or another allowed the offsring to survive and pass that caracteristic to their decendants in turn. Our love for babies and elders is one of those caracteristics that we as indivudials of a species have in common. That make us to want our elders to be with us as much time as posible, just becouse our affinity with them. This love for the elder have to be an advantaje that worthed to be selected by the evolutionary process, and this caracteristic is reflected in the tendency of the life expectancy to increase generation after generation. One could say, that those elders that age slower would be more likely to benefit from the love of their offspring, than those that age faster. On the other hand, to age slower may not make a difference at all, just because we love our elders despicte their physical appearance. I'm considering the cultural and technological advantages that allow our elders to live longer to be a product of evolution too.
So my question is wheter we are evolving to age slower, or to live longer aging at the same rate?
As a side note, we are becoming more like what they call a super-organism, as most of os can only benefit of a longer life spam by living in society. Just like an anthill or a beehive. If that is true, we are not evolving to age slower.
