If I understood your question correctly, the reason why we're moving differently than people in ancient history is that we have new available technologies which enable us to transport from one city to another via car, train, or airplane. None of these were available during ancient times. What remains the same, however, is that we still walk by foot for shorter distances, similar to our ancestors.
No nutritional supplements cant help to reduce stress.
Several vitamins and other supplements have been associated with reducing stress symptoms, including Rhodiola Rosea, melatonin, glycine, and ashwagandha. L-theanine, B-complex vitamins, and kava also help build the body's resistance to life's stressors.
Although it’s very important to eat a diet that includes all the vitamins and minerals you need to keep you healthy, vitamin and mineral supplements aren’t a quick fix when you aren’t eating right. No nutritional supplements really take the place of a glass of orange juice or slices of fresh fruit. Nor has it ever been proven that vitamin or mineral supplements will fight stress or calm nerves.

An agonist is a drug that mimics or increases the effect of a neurotransmitter.
An agonist drug works in a way that it binds itself to a receptor inside the cell or in its surface and then modifies the cells' function, where it amplifies or imitates the neurotransmitter.
There are many negative effects of agonist drugs. For instance, one experiences symptoms like trembling, nervousness and tension, headaches, palpitations and muscle cramps. Apart from this, it also causes nausea, hypertension and cardiac arrhythmia.
Agonist drugs can be of three kinds, full agonist, co agonist and selective agonist. Some examples of agonist drugs include heroin, morphine and opium.

Middle age is a stage of human life that is characterized by:
- People who are close to 50 years of age.
- People who are open to new learning.
- People more confident and less fearful of their decisions.
<h3>What is middle age?</h3>
Middle age is a classification to refer to a stage of life that is generally established between 50 and 64 years of age.
At this age, the adult is aware of what he has lived and what he still has to live. Unlike youth, people in this stage feel confident in making decisions and believe they have the necessary experience to make good decisions.
On the other hand, middle age is also characterized by adults who already have a stable economic life, which allows them to worry about other activities such as their hobbies or develop learning that they could not do when they were young.
