The operative word here about stress is that it is a perception, also known as a thought or point of view. There are objective stressors, to be sure. But how these affect us determines our body's stress response.
If time holds us captive, it simultaneously offers the key to our liberation. Our shackles belong to the past and the future. In the present moment there is no past or future that is not contingent upon our attention to exist. Learning to manage our attention is the best way to manage our relationship with time.
