Shadow of the Colossus Tips

In shadow of the collossus if you want to increase your health bar look up in the trees every time you pass one. Sometimes there will be fruit in the trees. Shoot the fruit down with your bow and arrow then switch to the hand and pick the fruit up like you would a lizard by crouching. You health bar will then increase. The increase isn't substantial but it adds up after a while. My health bar is almost 2/3 to the other edge of the screen.
