D. Because when you bite your nails your not in that type of mental state
The 1st American Volunteer Group (AVG) of the Chinese Air Force in 1941–1942, nicknamed the Flying Tigers, was composed of pilots from the United States Army Air Corps (USAAC), Navy (USN), and Marine Corps (USMC), recruited under presidential authority and commanded by Claire Lee Chennault. The shark-faced nose art of the Flying Tigers remains among the most recognizable image of any individual combat aircraft or combat unit of World War II.
The group consisted of three fighter squadrons of around 30 aircraft each. It trained in Burma before the American entry into World War II with the mission of defending China against Japanese forces. The group of volunteers were officially members of the Chinese Air Force. The members of the group had contracts with salaries ranging from $250 a month for a mechanic to $750 for a squadron commander, roughly three times what they had been making in the U.S. forces. While it accepted some civilian volunteers for its headquarters and ground crew, the AVG recruited most of its staff from the U.S. military.

weight if you are still living the same type of lifestyle that you were in
before the change occurred. If you have vices (e.g. smoking, drinking) before
losing the weight and you are still into them, then the long-term concern that
you will have is on your general health already. Vices affect how your body and
your organ systems react to the stimuli you put inside your body. If you cannot
give them up then be prepared to suffer more health consequences. <span>

Losing weight requires you to have a constant awareness about what food is good
and beneficial to you. Constantly choosing what and when to eat ensures
a continuous and healthy improvement in your body.</span></span></span>
