Going Through Puberty... at 12?

Times have changed in the world of Biology. In terms of Pubirity, it is not being set back but set early. way back when in the 1940's men and women would go through puberty till 17. Then 1970's they woulde reced to 15. But now in day people are going through puberty as early as 12 years of age.

Im not sure if this is something to get excited about or worried. One should never mess with the Body's natural functions. Yet the question is what is causig this severe change?

Some may say its evolution. Well that is wrong! It is all the Hermones and their improving power in our food. What iot use to take a farmer to grow a chicken in 4 months can now be grown in 3 weeks.

Pretty Nasty stuff. So the next generation is going to go through puberty at 5?
