So you're turning 40 but you are feeling 30?  What better way to celebrate and bring in this new chapter in your life than with friends on a cruise.  Treat yourself to a day at the spa, then, party like it' 1999!  You only live once, bring a friend, a spouse or that college buddy you have not seen since graduation day.  Hey your only turn forty once make is memorable. There are two ways you can handle this major milestone of turning forty.  You can put on your black dress sit in a rocking chair and mourn the good old days or you can, put on some flip flops, swim suit lay out in a lounge chair near the pool on the carnival Destiny and reflect on how wonderful life will be in the next forty years.  If you are booking your cabin today, I am guessing you are packing those flip flops right now, bring the black dress too it will go well with the lobster dinner.
