Are the mysteries in life what intrigue you the most?

It usually seems like everything is a mystery. Inside each uncovered mystery lies another.

The universe forming in such a way that self aware life could evolve was very unlikely. On the other end of the size spectrum the world of quantum physics is bizarre and mysterious.

Yes, I am intrigued by many mysteries, large and small. 

Yes

There are MANY mysteries : does God exist ; how do aliens visit Earth ; WHY does the universe exist ; how do ghosts, poltergeists etc. visit us ; how important is life in the universe ; etc.

We can guess the answers - and sometimes be right. Have proof ; which isn't accepted by others. Imagination is limitless. Perhaps what makes us interested in mysteries is also because we ourselves are one

"Sweet mystery of life At last I've found thee!"  Jeanette McDonald.  The mysteries of life are the most intriguing of all. We are but little brains in meat covered skeletal machines, on a rock, rotating around a star in a galaxy zooming through the cosmos, trying to figure all these things out. There remains much to amaze, awe and humble about our universe.

How time speeds up as you get older.

Mysteries in life intrigue me, but not the most. I think what intrigues me most are mysteries in life that despite being explained or debunked, are faithfully believed in. Why do some folks hang on to their beliefs with such tenacity is my most intriguing mystery in life? Two examples off the top of my head are The Bermuda Triangle and the kids trick Stiff As A Board

Edit. Unique Tim, absolutely, but as evidence for the rest of us not very convincing. Not that most people are making experiences up ( though plenty do just that) but eyewitness accounts are, to be kind, undependable, especially when time has passed.
