A period of 75 years is called a "septuagenary."
A period of six months is called half a year.
A period of 25 years is commonly referred to as a "quarter-century."
An atom that accepts an electron is called reduced because it gains electrons, which leads to a reduction in its oxidation state. In a reduction-oxidation (redox) reaction, the atom that accepts electrons is undergoing reduction, not oxidation.
In old age, there is a decrease in metabolic rate, leading to reduced energy production. There is also a decline in enzyme activity, affecting the efficiency of biochemical reactions. Additionally, changes in hormone levels and altered nutrient absorption can impact overall biochemical functioning in older individuals.

hibernation
The period when an organism growth and activity decreases is called dormancy. This is taught biology.
The Roman Empire's fall left Europe vunerable to the savage attacks of the Vikings and the tribes from the east. Christianity took over for some time, and then the Barbarian tribes from the east came into the west and moved the people further west-ward. After some time, the Vikings came down from the North and first attacked Lindisfarne and then the rest of the monastaries or what not. This era is called the Medieval Era and it goes on for hundreds of years.
This period if time is known as a recession.
In catatonic stupor, motor activity may be reduced to zero.
Raccoons do not hibernate but during severe winter weather they will go into a period of reduced activity and sleep in their dens until conditions improve.
Power-saving
That is called dormancy. During dormancy, organisms go into a state of reduced metabolic activity to conserve energy until conditions become more favorable for growth and reproduction.
The rabbit population will be reduced if there is a cold spring, because the rabbits won't be as active, and the food supply will be reduced. However, the activity of predators will also be reduced; so this factor will mitigate the reduction in the rabbit population somewhat.
