Well I can speak from experience when I went to my midlife crisis I was basically focusing on my career at which point there was confusing for me it wasn't clear as to what I want to do.
The correct answer is Chronic Strain. Based on research and
medical experts Chronic Strains are commonly caused by overusing and
prolonged/repeated movements of the body’s muscles or tendons. Repetitive
movement of the muscles and tendons may result to pain, especially if the
movement is inappropriate and improper. With regards to the given situation,
the pitcher repeats elbow movements in order for him or her to pitch the ball,
which leads to the main factor of overusing the body’s muscle that may result
to chronic pain.
Omg don’t be! Just know that if they are complaining about how you look. They’re just more insecure about themselves so they have to bring someone down to feel better. Just know you are pretty and you are worth it!
