A geroprotector aims to affect the root cause of aging and age-related diseases, and thus prolong the life span of animals. [ 1 ] [ 2 ] Some possible geroprotectors include melatonin , [ 3 ] carnosine , [ 4 ] metformin , [ 5 ] rapamycin , [ 6 ] nicotinamide mononucleotide (NMN) [ 7 ] and delta sleep-inducing peptide .
Possible senolytic agents are under preliminary research, including some which are in early-stage human trials. [6] [7] [clarification needed] The majority of candidate senolytic compounds are repurposed anti-cancer molecules, such as the chemotherapeutic drug dasatinib and the experimental small molecule navitoclax.
Trophallaxis: eating food regurgitated by another animal; Zoopharmacognosy: self-medication by eating plants, soils, and insects to treat and prevent disease. An opportunistic feeder sustains itself from a number of different food sources, because the species is behaviourally sufficiently flexible.
The largest living land animal, the African bush elephant, is a herbivore. This is a list of herbivorous animals, organized in a roughly taxonomic manner. In general, entries consist of animal species known with good certainty to be overwhelmingly herbivorous, as well as genera and families which contain a preponderance of such species.
Progeria is another example of a disease that may be related to cell senescence. The disease is thought to be caused by mutations in the DNA damage response, telomere shortening, or a combination of the two. [82] Progeroid syndromes are all examples of aging diseases where cell senescence appears to be implicated.

The species limit of human life is estimated by scientists at 125–127 years, [5] [6] and even in the most ideal conditions a person will not live longer due to aging of the body. Some scientists believe that, even if medicine learns how to treat all major diseases, that will increase the average lifespan of people in developed countries by ...
A heterotroph (/ ˈ h ɛ t ər ə ˌ t r oʊ f,-ˌ t r ɒ f /; [1] [2] from Ancient Greek ἕτερος (héteros) 'other' and τροφή (trophḗ) 'nutrition') is an organism that cannot produce its own food, instead taking nutrition from other sources of organic carbon, mainly plant or animal matter. In the food chain, heterotrophs are ...
