The blog, I like, is a scuba  diving blog. I am a scuba diver and I love to get more information about diving and underwater stuff. The site is about how people dove many, many years ago and what it felt like to be underwater. At that time the outfit was called ''Deep Sea Diver'' outfit and consisted of a big helmet and a suit.
You can also visit a museum with old diving equipment and many pictures. It will give you an idea how live was like and how people became diver.
It is always interesting to read diving blogs because as I said  , it gives you information and you can get an imagination of the wonderful underwater world.
