Civilizations in star clusters

Although deep within a dense globular cluster, stellar distances are
only a few "light weeks", say .1 light year, on the outer fringes, the
average distances might be say .5 light year and the planetary lifetime
much longer. At such short distances, at only a speed of .01c, such an
interstellar trip might be feasible in a beings lifetime.
Deeper within the cluster, planetary lifetimes might be too short for
native life to arise but sufficiently long for any civilizations
purposes if the civilization arises near the edge of the cluster.
Furthermore, interstellar panspermia would be very likely in a globular
cluster.
I wonder what the phsychology of space travel would be like for beings
situated in a globular cluster situated far from the main galaxy.
Would they feel themselves to ultimately be isolated somehow?

I wonder if life would evolve at all with all the stellar radiation
cooking the surface of any planets.
