From the article:
People who are jobless at some point during their lifetime because they were laid off, fired or quit may be at an increased risk of having a heart attack after age 50, finds a study out Monday.
Note that this means that a young person who has the above job-related stress may have heart problems later in life after the age of 50. It is a latent problem that may not manifest immediately.
It just so happened that I saw an article saying Sweden unemployment of young people under 25 being as high as 25%. I did not know Swedish youth unemployment rivaled that of Spain. Of course Greece's number is worse.
Will anyone remember to check the statistics 25 to 30 years from now? If this theory is true, these European countries will have an epidemic problem ahead of them.
PS. I remembered a statistics on nations' happiness level, which showed Scandinavian countries' rankings being fairly high. So, I checked again, and indeed Sweden ranked #5. How could that be, if its young people are jobless? These two facts seem so contradictory.
