What is Body and mind but vehicles fort the Path.

The physical body will no doubt feel the creeping effect of aging this is a fact of life that we cannot deny, however we do not get old at the same rate as some will age faster than others. Why? If a runner runs for miles and miles every time he sets out to run it is not the body that gives in first towards giving up, it is the mind. The body will endure for as long as the mind tells it that it is still doing fine and to keep on running but once the mind decides enough is enough, the body will slow down and eventually give up running. hence the same is true with the whole process of aging, the physical body will remain young and healthy for so long as the mind is young and healthy. it does not take an Einstein to figure this out. The human mind is a very complex and in lay man's term very tricky and slippery like an eel, it can turn the worse into the best and vice versa at the drop of a hat. The role consciousness and awareness plays in this factor is crucial as the mind is in need of constant monitoring and it is only under direct and constant scrutiny that the mind can be of benefit to the body's well being.
Talk to your brain cells and demand that it functions accordingly or better yet address the very molecules of atoms that makes up this body and make sure that all is well from the very basic of the building block, that all is in balance and functioning at the maximum output for the well being of the whole. Until you have learned to communicate with the most fundamental structure of your building block you cannot have a good control over the rest of your form and structure. The knowledge on how to go about doing this is available in abundance from all the various teachings of the ancient as well as modern schools and religions and again with the blessing of the Internet it is available almost at your finger tips. Again, 'Ask and ye shall be given', ask the right questions. demand the right answers. If you can spend 99% of your time talking to yourself why not make it worthwhile and beneficial, talk to your brain cells, you blood cells, your vital organs, your bones and muscles, give instructions and let it be known that you are aware and conscious of their workings. When you feel off the alignment like being excessively tired or fatigued, reason out why and see what is not in accordance, to hot or too cold, too much wind or too much of the earth element; the elements that makes up your body is again most basic. Earth, wind fire and water and the life force or energy that generates all these together. If one is out of sync the others will be affected; be aware.
Awareness of the mind and body synchronicity is the basic healing process for the well being of the human form and it is also the building block that helps to regulate and maintain a healthy mind and body prolonging the the sustainability of these vehicles of our existence. Aging takes place when these are not well cared for or negelected a whole lot faster than otherwise. Yes, we cannot stay  forever young and healthy but we can surely make it an effort to make it last longer. Couples with this awareness is the rest of the health  practices that goes with like well balanced diet and exercises and so forth which goes without having to be told. A vehicle left abandoned will naturally end up in a junkyard a whole lot sooner that one that is well looked after. The human from is a gift like none other for as the Buddha is said to have said, "IN this human form is the means for liberation, Don't waste time."   
Have a Good Day!
