Due to errosion from the sea waves, there are now only 7(or8?) left. You wonder why it attracts a lot of tourists. Its just a marvel to be seen in real life
I walked a lot and it didn't hurt one bit! I did have one walking stick with me because there were lots of unevenness in the ground.
Im glad for osseointegration because if i was still in a socket based setup, pressure sores and sweating would most likely be an occurance.
