The More Happy You Be The More You Live – Read On For The Proof

A recent study has revealed that people who are highly optimistic tend to live long life of over 85 years and more. The PNAS paper has the details which includes how the researchers tried to find out the relation between higher positivity and longer life while focusing more on exceptional longevity.

Usually all the research around longevity is focused around the role of biomedical factors and hence the study was more about the psychological factors that help with longevity. As per Lewina O Lee, PhD, and associate professor of psychiatry at the school of medicine of Boston University and the corresponding author brought up that there was very less study around the psychosocial effects role in promoting healthy aging.

According to her and team, optimism was “general expectation that good things will happen or the belief that the future will be favorable because one can control important outcomes.”

The data used for the research included 69744 females from Nurses Health Study (NHS) and 1429 males from Veterans Affairs Normative Aging Study (NAS) across the 30 years (1986-2016). The routine also included regular health survey about diet, smoking, alcohol and other health related behaviors and questions on optimism. While 71% of the males who participated died within the 30 years of their follow up, 13% percent of the female participants passed away within 10 years of follow up.

Here’s an example of one of the six questions that the NHS participants were asked –

Rate the statement on whether you agree or disagree “Overall, I expect more good things to happen to me than bad” on a five point scale.

The researchers then carried out an analysis of the data and discovered that the most optimistic males as well as females at the start of follow up lived 11-15% longer as compared to those who were least optimistic. The team also found that even after conforming to the health behavior results like educational achievement, depression, diet, doctor visits, smoking and alcohol, the associations still held true.

Some Amazing Scientific Inventions That Changed the World For Good

The medical field has evolved consistently over a period of time ever since the inception of human kind. It has definitely brought about a progressive change in healthcare. But, some of these inventions have apparently brought about a kind of revolution in the field. Here is a list of few amazing inventions that have helped mankind to core ever since they’ve been invented.

Scientific Inventions That Changed the World For Good

X-ray – Imagine treating fractures and cracks in the bones without knowing anything about it. Though an accidental inventions it has worked wonders since its invention by German Physicist Wilhelm Conrad Rontgen way back in 1895. He was actually working on electron beams when he accidentally discovered that he was able to see his bones outlines. The initial reaction of people and critics was not favourable but eventually it won him the nobelprize in the year 1901.

Spectacles – Though there is not much evidence about who was the inventor of reading glasses. It is known to have been invented centuries ago and become even more in demand in the 1800’s when a lot of books began to be printed.

MRI and CT Scan – Inspired by the discovery of X-ray researchers began to dig deep into the possibilities of body scanning machines. This ultimately led to the invention of C T scanner and eventually MRI machine. The CT Scanner came into existence in 1979 which earned the inventor Dr Godfrey Hounsfield a Noble Prize and scanned multiple layers within multiple X-ray images. Soon, another invention called the MRI earned a lot of appraise to the inventor Dr Raymond V Damadian with its ability to differentiate normal cells with cancerous ones.

Cardiac Pacemaker – It was invented in the year 1926 by two genius scientists of Australian origin Edgar Booth and Mar Hill. The design was extremely complicated and required a needle to be pierced in the patients heart chamber but none the less it miraculously brought back a still born baby. Present day, the pacemakers are much more advanced and come with a battery life of 20 years.

Prosthetic’s/ Implants – Ask anyone with a handicap, how life can be challenging every single moment and then about prosthetic’s or implants and you’ll see how it has helped them overcome these challenges to a great extent. It is undoubtedly a big breakthrough of science and has enabled many lives shun their crutches or wheelchairs and live an independent life. The first prosthetic was an artificial limb invented by Douglas Bly in 1858.

Well, these are just a few of the inventions that enormously helped the medical fraternity and human kind overcome their healthcare challenges and are still doing so.
