It is interesting to note that while all the studies referenced above showed a training induced increase in testosterone, the one study that did not show an increase (and in fact a decrease) had people doing a massive amount of exercise in one workout – 50 sets combined of squats, bench press, lat pull down, and leg press. These poor guys saw a decrease in both testosterone and free testosterone that lasted for 13 hours. It would appear that training past your limits can depress testosterone levels. Just something to remember next time you decide to do a marathon weight training sessions that is well outside your typically volume of training.
A 1499 entry in the Ming Shilu recorded that 13 Chinese men from Wenchang including a young man named Wu Rui were captured by the Vietnamese after their ship was blown off course while traveling from Hainan to Guangdong 's Qin subprefecture ( Qinzhou ), after which they ended up near the coast of Vietnam, during the Chenghua Emperor 's rule (1447–1487). Twelve of them were enslaved to work as agricultural laborers, while the youngest, Wu Rui (吳瑞) was selected for castration since he was the only young man and he became a eunuch attendant at the Vietnamese imperial palace in Thang Long . After years of service, he was promoted at the death of the Vietnamese ruler in 1497 to a military position in northern Vietnam. A soldier told him of an escape route back to China and Wu Rui escaped to Longzhou . The local chief planned to sell him back to the Vietnamese, but Wu was rescued by the Pingxiang magistrate and then was sent to Beijing to work as a eunuch in the palace.      
The challenge lies in the fact that agriculture must produce more food with less resources in a way that is environmentally sustainable, economically viable and socially responsible. The aspiration of the private sector in general and the MNEs of the F&A sector in particular is to achieve a 20% improvement each decade in terms of economic growth and opportunity, agricultural productivity and nutrition, while simultaneously reducing the environmental footprint by 20% (WEF, 2011, 2012). This gives rise to the question: Do large F&A companies (MNEs) have the ability to achieve this goal and, if so, how? With a view to unlocking the full potential of smallholder agriculture, access to affordable financial services is moreover essential in order to meet smallholders’ investment and working capital requirements. Rural financial markets and outreach are, however, very poor in many developing countries. So how can access to financial services be provided to smallholders?
