Why do cells have telomeres?

Why do telomeres get shorter every time a cell divides? What counteracts this shortening?

What role do telomeres play in aging? You may want to do some research into dyskeratosis congenita.

If telomerase makes cancer cells immortal, could it prevent normal cells from aging?

Do you think we could extend the average lifespan by preserving or restoring the length of telomeres with telomerase? If so, does that raise a risk the telomerase also will cause cancer?
