The one day has 8.0, pH, suppose a child which has 8.0 pH in first day, and this 8.0 pH one by one becomes divide in different systems, like water 7.0 pH, blood plasma 7.4 pH, muscles 6.1 pH, liver 6.9 pH, pancreatic juice 7.8 pH, and saliva 6.35 pH,
Child of one day = 8.0 pH = cool tendons, for fast supply oxygen to muscles
Child of one day = 8.0 pH * 365 day = 2920 = some heat of tendon and muscles
One year child = 2920 pH * 95 year = 277400 = too much heat of tendon and not supply of oxygen to muscles,
Fresh muscles = 2920 pH for one year child
Fresh muscles = 58400 pH for twenty year age
Broken muscles = 277400 pH old age
