Rather, the life-span of living entities is related to the state of their lives, and is completely changeable by altering the lifestyle. A living testimony for this is that on the one hand none of the scientists of the world have set a definite scale for the life of man, while on the other, in the laboratories they have been successful to occasionally increase the longevity of living entities two fold or even several times, and at times increasing it twelve times over.
They even assure us that in the future, by means of new scientific techniques, the life-span of man would increase several times more than his present one. The above discussion was in connection with the basic issue of longevity. Secondly: As far as the issue of food and water during this prolonged sleep is concerned, had this been an ordinary and normal sleep, we would have accepted the protestor's objection, for then, the issue would have been incompatible with the basic scientific principles.
This is because, despite the fact that the metabolic activity of the body in a state of sleep is much lower than that during wakefulness, however, collectively and over several years it would be very great. However it must be realized that in the world of nature there exist certain states of sleep - in which food consumption is extremely trivial - such as hibernation.
Hibernation There are numerous animals which sleep all through the winter and undergo what is scientifically referred to as hibernation. In this kind of sleep, the arterial activities almost come to a standsuntil with only an extremely feeble flame of them remaining alight. The heart almost stops beating, or to state it more correctly, its beatings become so feeble and inconspicuous that it can hardly be sensed.
In such conditions, the body can be compared to a large furnace, which, when turned off, has its pilot light left burning. It is evident that the daily fuel requirement of that furnace for keeping its towering flames alight could possibly cater to the fuel requirements for tens or hundreds of years of that intensely small pilot light (of course, this is dependent upon the flames of the furnace and that of the pilot light).
In connection with the hibernation of some of the animals, the scientists state as follows: If we were to draw out a frog in hibernation, it would appear dead - its lungs contain no air and its heartbeats are so feeble so as to be imperceptible.
