Being Type A Personality Can Hurt Your Health

  THERE'S a lot to be said for being a laidback type of personality. Scientists have already proposed that those of us who are Type As - workaholics, overachievers and stressheads - are more likely to suffer from cardiovascular disease. Type A personality behaviour was first described as a potential risk factor for heart disease in the 1950s by two cardiologists. They studied healthy men between the ages of 35 and 59 and concluded that Type A behavior doubled the risk of heart disease. While this results later proved controversial, a more recent study by the University of Wales College of Medicine of men between 50 and 64 years old did find a greater risk of heart disease for those who leaned towards a Type A personality. These days health experts believe that what is so dangerous about the Type A personality is hostility. If you're simply driven, but not angry, you may not be at any greater risk of disease. In fact, you may be perfectly suited to our dog-eat-dog world, especially if you play sport or exercise a lot to get out that A-type mania. But, if you have a lot of anger, watch out. You are more likely to suffer from heart disease, say scientists, as well as be at a greater risk of chronic inflammation throughout the body. Not surprisingly, you may even take longer to heal.  As if that's not enough to make you chill out, a new study by the University of Utah, has found that people who multitask the most are the ones who can least afford to do so. The reason - they are the opposite of laidback. For these do-it-all-al-once personalities, multitasking may be potentially dangerous because they are unable to block out distractions even though they think they are superior at it. So, if you want to live longer, and feel better, don't try to do a dozen things at once and don't get hostile, get happy.
