Aches and pains are just a sign of age right?
All the aches and stiffness you feel aren't a sign of aging.
IT'S A SIGN OF A SEDENTARY LIFESTYLE.
You sprain and pull things a lot more easily because the lack of use of those muscles/joints have led to it being weaker and stiffer. And when it's tight and stiff, it hurts more. You injure more easily.
If you've ever felt that pain or pull or twang doing "simple" movements, make an apointment to have it checked out as well as to strengthen that area. Don't wait until an actual injury incapacitates you.
An ounce of prevention is worth a pound of cure!
