I truly don't see any, especially in that MAGNITUDE !!!! Some small felling of pain is necessary maybe so we would know if fish bone got stuck in our anus or if there is an infection or something like that but in any other circumstance it has NO purpose at all

. The malignancies do not hurt for example unless they are so advanced that it is too late to do anything about it. And, while we were in caves, like that fact made any difference at all ! So, as one of my CRSs said - one thing that God designed badly

.
Regardless of who designed it - higher power LOL or nature - it is poorly designed and if we are made in an "image of God" , than "thank you very much"

And why evolution had such a bad course for our pelvic area in general is beyond me as a biologist !!!! Human females are the only ones having such painful and long deliveries too and with such high mortality rate at childbirth !!!! Do you know that in Africa one in 48 women dies during childbirth ????? So, it is not the truth that we have problems because of our "industrial" life stiles and bad diet and all that crap.
I would definitely choose to come to this earth as a big oak tree next time around

- don't want to deal with any of animalistic conditions , or deep emotions or organ systems - I will be one big happy tree

!!!!
