The dots on dice are called pips. In casino's the pips on dice are not indented, but are flush (flat), this ensures each side has an equal weight. But I would assume an average set of dice could would have some bias toward rolling sixes, since they always sit opposite one (the side with the least indents, and therefore the most material making it the heaviest side).

If a human did not age then they would not expire.

The process of ageing generates a gradual decay in the DNA contained within cells. When cells divide the process is not perfect and a few base pairs are lost from the end of chromosomes. This is usually not a problem as the ends are protected by long regions of "junk DNA" known as telomeres. These telomeres seem to have no function other than to protect coding regions of the genome.

When the telomeres have been degraded over several decades then any loss of DNA in each cell division may begin to impair gene function. This is the process of ageing.

In theory if ageing did not occur and the individual did not succumb to disease or injury, they could be considered immortal.

In cancer cells the enzyme telomerase becomes active to allow the cancer cells to divide indefinatly.

Hope this helps your quest for immortality

Hey Lana, Your question brings up two different areas of thought for me:  1. Human curiousity as it relates to knowledge and learning, and 2. Human interest in death or the morbid.

I think that overall human curiousity is an evolutionary advantage - the ability of our brains to seek and retain information and then modify our behavior has allowed us to be more successful at living and reproducing as a species.

Specifically, the rubbernecking example (not sure if rubbernecking is an international term, so if you're looking for a definition, here's one: http://en.wikipedia.org/wiki/Rubbernecking) that you give may have more to do with our interest in death and dying.  Although I can't stand gory horror films myself (you can find me only peeking through my fingers), there are TONS of horror flicks out there, proving that people will pay to watch blood, guts and gore.

Death is an inevitable consequence of life, and yet there is so much that we don't know about it that fascinates the mind.  New Scientist has a whole entire topic guide of content devoted to the subject here:  http://www.newscientist.com/topic/death

We also had a special issue tackling big questions, among them, what happens when you die. http://www.newscientist.com/article/mg19225780.075-the-big-questions-what-happens-after-you-die.html
