If we look at the stages in childhood development form birth to the ages of 2, A child actually adapts better than adult in the face of discomfort because at that tender age, he has no experience or definition of what is comfortable or not.
Basically one can argue that discomfort arise from pain or bitter experiences which we immediately want to put an end to, but the question we need to ask our self to better have a grasp of this feeble reality called discomfort is what make you uncomfortable in any circumstance or situation.
Then you can work towards it to address it.
Its all in the mind
