There is a research of "People who have no friend, is like to become death in early life".
Certainly, it might be right.
Communications with friends can activate our mind and body, and the same or different person's senses of value make our life be enrich.
When I suffer something, a friend who conform me and cure my ache is a priceless property.

However, I have one big question against the research.
Based on the research about "people who have no friend, is like to become death in early life". one unreasonable fact is coming.
"Why am I living still now?"
In my case, there is no problem that I was dead ten years ago.
