We all know that the moment hagaromo otsutsuki taught others the creed of ninshu, humanity became dependent on chakra flowing through their chakra channels to live.
If chakra dissipates everyone would be dead, D. E. A. D. DEAD!!
So no unlike brain dead, Chinese adle writers who continue to choose the path of people needing to foolishly extract chakra on their own, I'll use the obvious and correct way chakra is supposed to be!!
People shall have reserves, civilians have only enough to live their life, those who choose the shinobi path or clan shinobi either train to increase their reserves while certain clans have larger than normal reserves from birth!!
Chakra is store in a metaphysical tank behind the naval.
Factually, chakra is the automatic process of spiritual and physical energies mixing in the tank behind the naval.
Shinobi may learn to manipulate these energies touse chakra with different ratios.
Yin release or yin chakra, is spiritually dominant chakra.
Yang release or yang chakra, is physically dominant chakra.
Yin is said to give form to the formless, while yang gives life and substance to the formless.
Jutsu are created using both yin and yang release along with the five basic nature's, earth, water, fire, wind and lightning.
Kekkai genkai/ Bloodline limits are either genetically inherited abilities or should someone simply use the principles of yin and yang to do so.
Magnet release was created via studying shukaku's chakra, by combining earth release with wind release.
Also, bloodline limits can be spontaneous mutation in one's dna!
Their are other ways chakra can be used, chakra can be used to sense chakra of others this is mostly a yin base way of using chakra, along with genjutsu, healing is a more yang base way of using chakra, along with body strengthening techniques.
Senjutsu chakra is when someone mixes the world's own energy into their very own reserves of chakra in a perfect 3 way balance, to little and nothing happens to much and well you'd be quite dead.
Bijuu are amalgamations of natural energy created via hagaromo's use of the creation of all things technique by splitting the ten tails own chakra.
