I am reading an interesting article

I was reading an article in OCT 2008 ED of reader's digest. It told about a study,Britain's National Survey of Health and development.It began with 13867 babies born in 1946 and has been tailing them upto now.The writer, (one of the participants) in now 62.What gets me interested is that the effect of early life effects the later life of people.( big surprise, but it is interesting to see it have been proved scientifically)
It says that "There is almost a five fold difference in mortality rate between those who always have the best chance all along the way and those who have had the worst.There are two groups who are doing well,Those who have always had the best things in life and those who are resilient, despite not having had the best thing in life, they still seem to come out on top.But the number of people who went right from the bottom to the top is few."
It is interesting to note that luck, karma or whatever it is called, is the most important thing after all.People are categorized as soon as they were born.Even though some people can break through the rank impose on them by life, they are minority.
It is weird to know a study like this exist.
