I always joke: people who are active need physiotherapy, but people who are inactive REALLY need physiotherapy!
Don't be cheap when it comes to your body, your body will get expensive revenge on you in the long run.
Healthcare is like food, it just costs a certain amount that needs to be accounted for. It's not a want, it's a need. It's that simple.
Sure, it would be cheaper in the short run not to pay for physio, massage therapy, medications, dental work, orthotics, and psychology services; however, it would also be cheaper to live on only white rice, but your body would fall apart from scurvy, rickets, kwashiorkor, anemia, pellagra, whatever.
The spending you need to maintain your nutritional health is no different than spending on other health necessities.
Just accept it and take care of yourself like a proper ass grown-up.
