Too simple, cheap, easy, obvious bias
The bias against things anyone can have at any time, that nobody can make much money from, because they seem too easy, too obvious, too simple, too cheap. The bias against the following solutions because nobody is marketing or can market them to you for very much profit:
Water
Gardening
Walking
Stretching
Meditation
Sitting in the sun
Fresh air
Curiosity
Vegetables
A good night’s sleep
Gratitude
Nature
