There are psychological 
researchers who do a lot of work
just on the brain and how it
functions and neuroscience
and genetics and epigenetics.
There's a lot of psychological
work going on there.
There are psychologists who
focus more on the individual
and their behaviour
and understanding that.
And then there are psychologists
who look at the individual in
their social context and looking
at behaviour in terms of the
impact not on the
individual, but also on their
social relationships.
So psychologists' work really
cuts across the whole lifespan 
from pre-birth to death, but
also cuts across functioning
from a biological and biochemical
aspect to the psychological
and social and cultural
aspects as well.
So I think psychologists are
ideally placed to understand
how individuals are functioning
in their social environment
and the extent
to which they're,
you know, living the life
that they want to live.
