Special Forces originally began during the Second World War as a means of carrying out specialist military operations often against more numerous enemy forces. Some of the highest trained special forces can trace their origins back to that conflict, like the Special Air Service (SAS), the Royal Marine Commandos, and the US Navy SEALs and Delta Force. Special Forces need to have a higher amount of training to be able to carry out their specialist missions. Such units need to have greater fighting skills, as well as extra training to have the best chances of completing their missions.
Currently the highest trained special forces include the British SAS and the Special Boat Squadron, Delta Force and the SEALs, plus the Parachute Regiments of most countries. The SAS made a name for itself in the jungles of Malaya, fighting the Irish Republican Army in Northern Ireland during the Troubles, and perhaps most famously ending the Iranian Embassy siege in 1980.
Delta Force and the SEALs like the SAS have been heavily involved in the operations against Al-Qaeda and later Isis. The SEALs most famously finding and killing the Al-Qaeda chief Osama Bin Laden. these operations showing the benefits of being so highly trained.
According to the US Department of Health and Human Services, one in every five teenagers has some sort of mental health disorder. While anxiety is the most common disorder among children and teens, depression — like bipolar disorder — most commonly appears during the teen years. It may be difficult to distinguish between depression and negative emotions resulting from lack of sleep, social problems, and hormones, which are also normal for young people. Teens who are depressed rather than sad or distressed may be unable to enjoy being with friends or eating, and may have trouble sleeping, making choices, or concentrating — without reason.
Other common mental health problems in adolescence include anorexia or bulimia, learning disorders, and addiction. Teen girls from 15 and up, in particular, are susceptible to eating disorders due to social pressure and body image issues, while youth of both genders might face addiction, as they begin to be exposed to alcohol and drugs. Approximately 3 percent of teens suffer from eating disorders, while up to 5 percent have attention-deficit/hyperactivity (ADHD) disorder.
Although there is still a tendency to stigmatize mental illnesses, the modern world is beginning to understand that mental health problems, especially in adolescence, are common, treatable, and deserving of attention. With help, the vast majority can go on to lead happy, meaningful lives.
