B: when relaxed, the diaphragm is a dome shape. when we inhale, the diaphragm flattens down, increasing the thorax volume. this reduces the pressure in the thorax, so air moves into the lungs to equalize the pressure. when we exhale the diaphragm moves back into its relaxed dome position.

icang [17]

For HIV/AIDS awareness program, South African Government has a plan targeting on the reduction of HIV/AIDS cases in future as well as treatment and lessening the impact of existing cases on all levels. For this the government is using all methods including public awareness, treatment availability, research on improving the conditions etc. HIV/AIDS is one of the most critical issues of South Africa.

Road Accident Fund or as that is generally known RAF. People who suffer serious accidents on the roads benefit from this fund in case of a serious injury, loss of an unborn baby, loss of a body function or any similar damage. The fund also support those who die in the accidents in respect of supporting their funerals and bearing the expenses. If someone who is the sole bread-winner for a household dies in an accident (not causing himself the accident) the fund supports the household also. There is also a provision for the one causing accident lest he be mistreated or unjustly penalized by the victim. 

The South African government has started a road safety platform named “Arrive Alive” since 2000 under the South African Government's Department of Transportation. The platform has helped built pedestrians sidewalks, cross-ways above the highways to lessen and eventually end the accidents and fatalities which are caused when people try to cross the roads. In addition to that the government has also supplied telephones with roadways to help those driver who face a break down on the road.  

16 days of activism against women and child abuse started in 2008 by South African Government. The government implemented many policies to help the victims as well as protective policies and rights were included in Law to help reduce the incidents. There are laws which do not allow any discrimination based on gender or race.

1. True or False: There is a medical explanation for binge eating.
VladimirAG [237]
1:I would say true, because every eating disorder has a explanation on what can get you towards the disorder, though everyone who has it might have got it differently. I wouldn’t say it’s like a certain food though, because it can be with anything.
