The meaning of life

As you can see from my 'Sites I Visit' section, I browse a lot through the site www.damninteresting.com. One article a few days back really caught my eye and set me thinking.

Reanimated Rodents and the meaning of Life

Basically this article points out the research carried out by some scientists in which a rodent was frozen for some while until its bodily function stopped, kept it frozen for some time and then brought it to life again.
This article made me think as to what 'life' means.
Is it a stopping of bodily functions like breathing and of the heart. Then what about the aforementioned case? What also about people shown on some channels who 'returned from the dead'?
Or is it the leaving of the soul from the body. In such a case how do you decide who's dead and who's not? What about the Near Death Experiences(NDE's)?
What about brain-dead people? Should they be classified as living or dead, considering that all their other organs are running, albeit by external stimulation?
I don't believe there is a definite answer to this question, particularly because there are a lot of blank areas that need much greater understanding than what we currently possess.What do you think?

First post

This is my 3rd attempt at blogging, the previous 2 having been abandoned by me after just one or two posts. I don't know how successful this one will be, but I sincerely hope this one does not fade away like the previous two.
What will this blog be about? This blog intends to present my viewpoint on the various ongoings in the world as well as anything interesting I find on the internet. I do not intend this blog to chronicle my life, because I don't think it is interesting enough to be chronicled. Motivation is a big issue for me, so I hope to have a few comments from you, the reader, to help motivate me in posting in this blog.
That's about it for this post.
