Lifting Weights, Effects of High-Impact Cardio Exercises Like Dancing, Wrestling and Excess Massages
Muscles will tend to feel sore by the time you reach 45.
Back muscles will tend to, especially, feel painful.
Recommendation to minimize or lessen the pains:
If you have to lift weights or things, make sure to get rest after.
Sleep once you get the chance and nourish yourself with food free from poisonous substances.
If you are in charge of driving a vehicle, make sure that you are wide awake when you drive or fly.
Have a co-pilot or another driver with you when you are on your journey, especially for long distances.
