Romantic love makes your nerves grow, provided you do not give it longer than one year, reports Wikipedia on romantic love and NGF, the ■Nerve Growth Factor:
Studies found NGF blood plasma concentrations significantly higher, in individuals who had been in a romantic relationship for less than 12 months.
■Psychoneuroendocrinology is a journal to join neurology, endocrinology, and psychology — the neuron, the gland, and inevitably a symbolic ego.
For a symbolic exercise, I’ll be reading now on as if I were 15 years old; I’ll be growing up along with the post.
The journal says,
In view of the complexity of a sentiment like love, it would not be surprising that a diversity of biochemical mechanisms could be involved in the mood changes of the initial stage of a romance.
The NGF for (a) people to have just fallen in love is 227 pg/ml; (b) those in a long-lasting relationship, 123 pg/ml; and (c) for singles, 149 pg/ml.
At 15 years of age…
Long-lasting, fond, and mutual affinity is the worst circumstance for NGF or love, or both. 15 is the age you may feel ■Owner of the single heart should have been the song.

NGF can indirectly stimulate the expression of adrenocorticotrophic hormone (ACTH), by increasing vasopressin, adds Wikipedia to the picture.
For long and scientific words, we can copy them and paste into Merriam-Webster online. The dictionary says adreno•cortico•tropic is something that acts on, or stimulates the adrenal cortex: ■Merriam-Webster online, Adrenocorticotropic.
17 is more analytical
Although full maturity cannot be everybody’s purpose, let us look up what a part does. An adrenal gland produces the hormone epinephrine, says the ■Merriam-Webster definition for kids.
Epinephrine is a ■stress hormone. It is part in the body’s fight-or-flight response, ■explains Merriam-Webster. The dictionary ■does not have “romantic love”, but if we even just casually browse online for epinephrine, it will come up a suspect in “voodoo deaths”. Another name for epinephrine is adrenaline.
18
It is certainly the age to disbelieve anything purely “psychogenic” or “psychosomatic”. Deaths were noted regardless of culture or geography, in camps — concentration and prisoner-of-war. Purely psychological fear likely does not exist, and adrenal hyperactivity has been recognized with lesions to the kidneys.

This age already loves homeostasis. Excess epinephrine kills. Vasopressin is a homeostatic, working in remembering as well as forgetting, along with bodily levels for sodium (as from kitchen salt; Vander et al., Human Physiology, 1985).
The LVP (lysine vasopressin) and placebo groups showed an enhancement; we yet cannot claim a memory enhancing effect of LVP, because placebo treatment enhanced memory performance to the same extent, say researchers.

A homeostatic beyond doubt, the above means. Saline was the placebo.
20: why grow nerves for love?
A nerve is an enclosed, cable-like bundle of axons (nerve fibers, the long and slender projections of neurons) in the peripheral nervous system.
In the central nervous system, neurons are sometimes called nerve cells, though this term is potentially misleading, since many neurons do not form nerves, ■says Wikipedia absolutely without error.
30 years old and on
Long as it takes, though we might suspect some implications were omitted from a dictionary for kids, we remember that blood samples were taken from men and women whose lifestyles varied on muscle activity.
Those freshly in love were the most outgoing, and settled within more or less 12 months. Those in long-term relationships shared everyday duties, and spent more time relaxing together. Those living single did not have a partner to partake in the household. That group was between the two others, for NGF.
Memory and relevance
The more advanced, the more focused on relevance the human age is. There are people who never got their hand in fire, having been simply told it could not be a good idea. There are those without memory flashbacks, having learned mineral supplementation. No people, however, would hold own linguistic memory for irrelevant to own memory overall.
Says Wikipedia for the subheading Memory,
Cortisol works with adrenaline (epinephrine) to create ■memories of short-term emotional events; this is the proposed mechanism for storage of ■flash bulb memories, and may originate as a means to remember what to avoid in the future.[34] However, long-term exposure to cortisol damages cells in the ■hippocampus;[35] this damage results in impaired learning.
None of the above is good and thus relevant to human memory of language. Stress obviously is not good for learning, ■WebMD affirms.
Homeostasis needs no stress
Cortisol is yet relevant to learning as a steroid, namely a glucocorticoid. Aldosterone would be a mineralocorticoid also as a result of corticosterone conversion, whereas zona fasciculata and reticularis are a proved opposite profile (Vander et al.).
The “problem” here is exactly the same as with vasopressin above, no stress is required for the homeostatic action. Hopefully, medical sciences will depart from studies via privation.
Fortunately there is physical exercise, for love of neural health today.
