It is not fully understood, but this is no surprise as complexities of brain activity are still far from being unravelled and understood. The brain holds far more secrets than we have discovered. What is known is that sense of smell is registered in a part of brain which was already developed in our earliest ancestors.

The limbic area of brain was well developed before man had power of speech or was able to make tools. The limbic area is concerned with all those activities vital to survival in a sometimes hostile world: sleep, hunger, thirst, memory, sexual response and, or course, smell are all affected by limbic system.

As modern man developed 'higher' senses and brain became larger to accommodate development of speech, intellect and creativity, ancient knowledge became blunted or buried deep in unconscious and limbic area of brain lost some of its importance. But that ancient knowledge is still there and needs only to be re-awakened.

Essential oils have power to re-awaken and stimulate limbic system and aromas can be used to excellent effect by aromatherapist.

I do love biking. As a child I would go on late night biking around our village just to feel exhilaration of experiencing a different kind of freedom. Biking gives me a sense of awareness over every part of my body being alive and active. I dread day that I’ll grow old enough or be paralyzed and unable to ride a bike anymore! Oh, but it is dreadful to be deprived of pleasure of riding a bike, again!

It’s quite good to note then that some people are appreciative of bike for paralyzed, reported on BBC news on November 15, 2004, like Eleanor Freewheeling has expressed at http://ewheeling.over-blog.com/article-17631.html on November 23, 2004.
