There is nothing like living in sunshine and having a pool to
swim in each and every day.  Jo Beth was working nights as a
programmer, and had all day to lounge on a raft in the pool.  
Bliss!  She couldn't have been happier.  

Jo Beth slept when she came home until the sun rose.  Then,
she'd get up long enough to put on her suit, and move to the raft
to finish her "night".  That left her the whole afternoon to visit
with new friends, shop, or whatever.

Pretty soon, though, Jo Beth found that she was sleeping more
and more.  She was sleeping so much and so hard that she was
having trouble waking for work.  She began to have trouble
staying awake AT work.  

And she began getting these awful headaches...
Lounging

Where Jo Beth gets really, really tired and achy.
