Lack of liquid circulation & Tripods

Unfavorable weather condition this morning decreases the brightness around even after dawn. Pushing away rainfall, I am going out for visiting some art exhibition where my acquaintance is doing. Staying in front of computer LCD brings me some physical dysfunction on right toe probably because of lack of blood supply. Body liquid circulation is not enough and the physical property of connective tissue is not favorable, deformation repulsive force disappears, viscoelasticity is decreasing. This kind of changes in the property of subcutaneous tissue resembles that of Economy Syndrome. Both of them are caused by staying in the same posture for a long time because of so-called lack of exercise. As a proof, local massage and muscle actions recover the ill-condition. The older we get, the  more care is required to keep healthy condition, it's an inevitable phenomena at all. The necessity of careful consideration for elderly can only be realized at that age as I did.

The tripods used in photographic field are deserted by the former users probably because the remarkable improvement of Anti-camera shake mechanism invited by most of the Digital Cameras. Consequently, incredibly, worthy ones are sold at the minimum prices. Foreign made expensive one produced half a century ago appears sometimes and most of them had not been used just kept unused. I often pick them up on the item that is too good to be missed. I have piled some of them without stubbornness, careful checking of their construction, the principle of the mechanical designers are discerned, creverer copying are observed sometimes.
Probably, the latter engineer must have disassembled the former one and studied. But, most of the case, copied item never exceeded the predecessors. because the follower does not know the pain of the birth of the creation. Easier changing of arrangement without deeper consideration leads to quality deterioration.
