On August 27, 2021 is Just Because Day. Why? Just because! It is believed that it was founded in 2005 as a chance to do something without a rhyme or reason. Reason is the ability of the human mind to form and operate on concepts in abstraction, in an ordered and usually a goal-oriented manner. Often you do something because you have to, or you want to, or it's expected of you. None of those applies today.
If you've ever wanted to act on a strange impulse but without any logical motivation to do so, normally you still don't. But don't let that stop you on Just Because Day! You could start with the first thing that comes to your mind. Maybe you think about buying something without a need, think about walking backwards or throwing spitballs on the floor. Just feel free to do this just because.
