I'm 39 and a I've been healthy all my life.  Lately I've been having
these body feelings such as the one you get before getting sick with
the flu; it does not hurt, there's no cough, no runy nose, no fever,
just a physical feeling of losing energy; this has happened for two
weeks so far and it happens everyday for a few hours intervals.

Is this because age? any suggestions?

Thanks much

Jon Barnet
