There are many common human experiences and feelings that we all have, but lack the words to express. Discovery Digital Network's YouTube channel TestTube aims to combat this, one word at a time, with the new series Dictionary of Obscure Sorrows.

The series focuses on words that describe those quiet and sad sentiments that give us pause. Watch the video above to learn about Oleka, the fear that life is short and impossible to hold on to. The video explains the word in detail with footage shot with a GoPro to accompany the dialog.
