life in the third world countries for many people is a heavy struggle. I would say for a majority it is a struggle and surviving day by day. HIV and AIDS in Africa, lack of basic food, lack of medical supply and medical care, minefields, where anyone can be killed, injured and lose their limbs, endless wars and hate crime against children and women, sweat shops, where children as young as 8 years old can work 10 hours shift for several pennies a day, and etc. is a part of everyday life in many countries around a globe.
My mother used to constantly tell me: "Nobody ever said life was easy". Well ok, fine. But she neglected to notice or point out all the joy and wonder and beauty around here. She only seemed to want to focus on the bad. She could have at least said something like, yeah, it's hard, it's tough, and sometimes, it hurts, but, oh, baby - it is SOOOO worth it!
My dad expressed a lot of childlike wonder, especially towards the end. Even though he was a physicist and an atheist, we really shared a lot of joy and giggles during the time we spent together during his last ten years.
I understand there is a lot of suffering in this world. It seems to me, if a soul like my own were offered the chance to come back to earth and have a body, with the condition or stipulation that it would be under miserable conditions like some of those you described, but it was either that or staying put on my cloud listening to the same repetitive music in a loop that Bob Monroe described, then personally, I would jump at the chance.
