With the rapid advancement in bioscience and technology, it is likely that most ailments will be cured in the future and our life span would increase considerably.
With increased lifespans, there are new challenges that would need to be overcome. One could plan ahead and accomplish tasks that would take decades or centuries, unlike our current mindset of relatively short-term goals. An extended period of existence would make us wiser and afraid of taking risks.

As the human life span increases to span centuries, the planetary environment, along with the collaboration and cooperation among nations would come to the forefront, as hostile people and chronic pollution are extremely dangerous in the long run.
While our survival would still not be a guarantee, there will be a new challenge of overpopulation, which could be moderated by sending people into space to colonize other places, and by limiting the birth rate.
As inter-galaxy travel becomes a reality, there could be many spaceships which would be able to take us to nearby habitable solar systems, setting up for new adventures, challenges and a completely radical lifestyle.
The changes in Earth’s biosphere could also be a concern, as new technologies and constant harvesting of resources (like deforestation) can lead to dangerous environmental changes.
When we look at the problems we may face if we live a million years, we start to realize that the current problems and concerns are nothing when compared to the long-term perspective of our planet and the universe which we inhabit.
The constant injury humans cause to our home planet would seem childish and stupid, when seen alongside the larger picture of where we are in the universe.
What is it about brain matter that gives rise to consciousness? In particular, the neuronal correlates of consciousness (NCC) - the minimal neuronal mechanisms jointly sufficient for any conscious experience.

Before, during or after an important event, we often perform symbolic behaviours, or rituals, that are of different shapes and forms. These acts often look superstitious and irrational. Many are practised in either a communal setting or in complete solitude.
The desired outcomes for these rituals can be to remove anxiety, boost confidence, or for improved performance in a competition. The surprising thing is that rituals are more rational and scientific than they appear on the surface, and are also effective.
