Meaning of Senectud
What is Senectud:
Old age is the last stage in the life of a human being characterized by biological aging.
The word senescence originates from the Latin noun senectus which means age and in turn of the verb senescere which means to grow old.
Senectud is used as a synonym for the elderly, the elderly, old age, the elderly and the elderly.
The senescence concept comes from the name of the ancient Romans to one of the 7 vital phases of life called senex, which means 'older' and which was between 60 and 80 years of age. Senex was considered to be the phase where wisdom and sententia (the age of judgment and opinions) are reached.
The Romans called each of the 7 vital phases of life as follows:
- Infans: 0 to 7 years old.
- Puer: 7 to 17 years old.
- Adulescentia: 17 to 30 years old.
- Iuvena: 30 to 46 years old.
- Senior: 46 to 60 years of age.
- Senex: 60 to 80 years of age.
- Aetate provectus: over 80 years old.
In biology, senescence refers to the phenomenon where human cells no longer proliferate after 52 divisions. The American Leonard Hayflick (1928-) postulated in 1956 that the number of divisions of human cells are limited, considered as one of the causes of old age or senescence.
Characteristics of senescence
The variations in the rhythm of senescence in each person is determined, among other things, by their biological age (functional age of our organs and systems in relation to normal aging) and their chronological age (age of our body since birth).
Some of the characteristics of senescence are:
- Elevation of blood presure
- Increase in higher levels of "bad cholesterol" or low-density lipoprotein (LDL).
- Thinner and less flexible skin due to the gradual decrease in collagen.
- Muscles, connective tissues, and bones weaken.
- The sensory organs are losing their functions (vision, hearing, touch, palate).
- Gradual brain deterioration.
- Sexuality can be fulfilled by higher levels of emotional satisfaction and physical pleasure.
- Menopause in women and andropause in men.
