Eat, drink and... breathe? We neglect this last one.

Have a look at physiological needs:

Eating
We spend so much money on eating good, eating well.
Tons of content explain recipe of food, tell things about ingredients, etc.
Eating is social, religious, ethological...

Drinking
Same as eating.
Juices, wine, beer, cider, sake, whiskey, sodas.
Drinking is central in every culture.

Sleeping
Look at the bed industry.

Warmth
Big topic. Leads to textile industry, heating.

Sex
No comment.

Breathing
...
Breathing what? Yes we breath and so what?
Nobody cares. We totally neglect breathing.
We don't consider it as something we need to care of, work on, learn, enjoy.
As there is nothing to sell I guess, breathing is forgotten.
Other physiological needs pitched by Maslow are the center of universe but this one is rarely discussed.

Let's give breathing the same value as eating, drinking or sleeping!
