The reason I am against caving is because many things could happen. In fairness none of these things happened to me but they could happen. The first thing is injury, You could fall down and you can easily hurt yourself and even if you have supplies to heal the womb, It still won't work.
Second reason is earthquakes. If you have that much bad luck and an earthquake happens you are in serious danger! Rocks can fall on you and you can easily die or get a serious injury, A big chance you won't survive.
Third reason is you can break a bone, if you break a bone and you have to climb in the cave, you might as well safely go back.
Forth reason if you can slip and fall, Your lights can go out and you won't be able to see where you are going.
