Growing pains

Most major airports have a facility where luggage left behind by travellers is stored

The most interesting aspect about human beings is our ability to evolve. Scientists believe that our entire species may have slowly evolved from nothing more than microscopic single-cell organisms. Mankind was once so new to this world that the most advanced discovery for us was learning how to build a fire. Now, we have the ability to control entire cities and countries without moving an inch.

The individual unit of a species acts in a fashion that is not very different from the way it behaves as a whole. So, in the very manner that our species has evolved as a whole, we too, evolve individually from the moment we are born. We call this evolution, growth.
