The "interconnectedness of all things" is a notion embraced by the spiritual community and, more recently, by science in the field of quantum mechanics.

This area of research is still regarded as largely theoretical by the scientific community, however, unlike the "nuts and bolts" science that focuses on improving our medical and technological knowledge with solid, peer-reviewed studies.

But sometimes things smell good too. But our ability to smell deteriorates over the years, sometimes as early as age 30. By age 60, about half of us will experience a reduction in our ability to smell, and by age 80, about three-fourths of us will.

A bad cold can knock out your ability to smell–maybe even forever. From 3 to 4 million Americans have been diagnosed with anosmia, the complete inability to smell, and hyposmia, a reduced smelling capacity.

We understand why we perspire when we’re exercising–as our sweat evaporates, it cools off our body. But why do we sweat so much when we’re under stress? And this is the really stinky kind of sweat, the kind we apply deodorant to try to stave off.

And we’re under more stress than ever: Americans spent almost $3 billion on deodorants and antiperspirants in 2011, an increase of 13% from 2008, when the current recession first hit.

But we humans can’t smell it – Odors that represent food or indicate danger are capable of altering an animal’s lifespan (and ours too?) by activating a small number of highly specialized sensory neurons in our brains. Does this mean that in order to live a long life, we should surround ourselves with good smells (rather than bad ones?)

Smells can impact a wide range of health-related characteristics including athletic performance, type II diabetes, and aging. Nematode worms and fruit flies that were robbed of their ability to smell or taste, for example, lived substantially longer. However, the specific odors that control this effect on aging are unknown.
