If you focus your eyes on a moving object, you feel that it moves at a slower pace, compared to when you are just looking without focus. The more is your mental focus, and the more relaxed you are, the object "appears" to move slower. Many say that it may even "appear" larger. (I had mentioned this before in [this post] about watching snow!]) At high levels of concentration, this called entering the "zone" in sports jargon.
We have all experienced periods in our lives that everything seems hectic. Events attack us from left and right, and we feel stressed out and worried all the time.
My conjecture is that, in such cases, if we start focusing on what is happening in the moment then things start to slow down, and we can handle each one much easier.
