I had the opposite experience :(
Woke up Tuesday morning and performed the foolish genuflective act of opening my eyes. TWANG! My back popped like a guitar string. Took two days to recover (I wasn't immobile, just in pain all day).
Many fears are born of stupidity and ignorance -
Which you should be feeding with rumour and generalisation.
