I spend a fair amount of time maintaining flexability and strengthening the core which is what holds everything together.
I enjoy travel or books about different parts of the world. Two paired books I've enjoyed are "The White Nile" and "The Blue Nile" written by Alan Moorehead, an Australian corespondent. These books are about the search for the source of those two branches of the Nile during the exploration of Africa. They are beautifully written and read like a great adventure, which the exploration of Africa was. They were written over 50 years ago so may no longer be in print but should be at a library.
