You can call it a day and spend time reminiscing all those mad rat races against time, braving all odds, which give you the reassuring feeling that you have run your race well, reaching the finishing line, without sacrificing the values you hold dear in life. What else one needs in life?

Evolution is a process which continues time after time. Like eras.
Mohicans ended and Apache era emerged.
Chola ended and Chera era came up.
Chera soon ended and Pandya era blosommed.
Wild West era ended, Injuns settled down and Whites emerged.
................... and it continues till the end to everything in this universe occurs, yar.
