I find it very strange how a maufactured product such as "metal" can be found in some meteorite samples, especially when you consider the strict processes involved to make metal in the first place. If anyone can explain to me how these metals happen to be in meteorites, I would appreciate your answer !

I am not giving an opinion , I want some. I have heard different arguments about the space shuttle , most of them about what a waste of money that it is , that the government should take care of people here instead of spending millions on a space program. Then there are those that say it could someday improve the way we live or even save the human race. The only opinion I am giving is , i live a few miles from the cape and it sure is awesome to see it go off at night. I would like some opinions though to see if the ratio of pros and cons.

I came across in some souther parts of India that mother's milk are collected and taken in small quantity by some men of the age group (25 to 45)and they informed me that the mother's milk contain most of the preventive natural medicines. Therefore they collect milk of mother recently delivered child (and pay costs for this to) in small cups and drink. I was further told that such people do not get affected with mosquito and other virus fever and have full potency too. I find that even middle aged ladies too adopt this practise. I find that mother's milk is collected and used as a medicine in eyes for boils on eye lids. For hadache it is also applied on foreheads. There is strong feeling that the mother's milk may cure such ailments. Will all these be correct medically.
Will it horm the person who consums it?
