Benefits related to air

[Julian-Dumitrascu]

Unless one wants to have a close look at this scientifically, one doesn’t ask why we breathe. We simply breathe. We live as long as we breathe. We can call breathing one of the fundamental benefits or, rather, one of the basic things.

1. What challenges us to breathe healthily?
   1.1 The causes of respiratory diseases
   Deaths from respiratory diseases occur mainly in older adults.
   In 2019, 7.7 million people died of respiratory diseases:
   a. chronic obstructive pulmonary disease: 3.3 million deaths
   b. Lower respiratory infections were the world’s most deadly communicable disease: 2.6 million deaths.
   c. Trachea, bronchus, and lung cancers caused 1.8 million deaths.
   They say that chronic respiratory diseases are not curable.
   It seems that a coronavirus killed 7 million people during the next 4 years.
   This can mean that at least 14% of people have been dying because of how poorly they had breathed.
   1.1.1 tobacco smoke
   They say that is it useful to avoid smoking.
   1.1.2 air pollution
   This can mean that fire is deadly.
   1.1.3 infections with viruses or bacteria
   About a quarter of the population is estimated to have been infected with tuberculosis bacteria.

2. How do we improve our chances of breathing healthily?
   2.1 We can help people to avoid smoking.
   We have sold nothing that would help people smoke. We find it difficult to decide to sell e.g. cigarettes.
   2.2 We can help people to spend time in places with better air.
   Pakistan seems the country with the worst air.
   2.3 One wants to work and have fun in air within a certain temperature range.
   People seem more comfortable when the air temperature ranges between 10 and 30 degrees Celsius. Which temperatures do you like when?
   It seems that one could live naked at temperatures between 25 and 30 degrees, in at least a dozen countries: Thailand, Somalia, Eritrea, Saudi Arabia, the Philippines, Guinea, Suriname, Malaysia, Nicaragua, Guyana, Belize, and Indonesia. Some of them have been called heavenly. Of course one feels in heaven when one has plenty of warm water, warm air, and food! Other things than stoves and soot are on one’s mind.
   2.4 People seem more comfortable in air with a humidity between 65% and 75%.
   According to data collected approximately between 1960 and 1990, Gabon was one of the most humid hot countries. It seems to have more than 96800 square metres of forest land per inhabitant. It is becoming more challenging to live in such places because the humidity and the temperature of air are rising, and we need to sweat so that we don’t overheat. Overheating kills beings. The air speed averages 7.8 km/h at the height of 10 m; this is one of the lowest averages; it is difficult to cool off.
   Sudan seems one of the countries with the driest air, and it’s hot. The air speed averages 21.8 km/h; this is one of the windiest countries in Africa.
   2.5 It seems that the global average of air speed is 8.14 m/s (29.3 km/h), and that people like air speeds between 9 and 22 km/h.
   Chile and New Zealand seem the windiest countries.

3. Wind energy
   Global average wind energy at the height of 100 m: 435 W/m2
   It is difficult to use wind energy in the Equatorial Guinea and Gabon.

4. We can discuss what sound environment we want.
