A body is just like a car's engine,some times its in the most optimal state functioning well and sometimes its poor in performance.
If a car's oil is not monitored and maybe it gets dried,the engine dies or becomes faulty so also the human body,it has to be monitored in other to know what could be wrong with the body.
At times we keep postponing our scheduled appointment with the auto engineer,we may say the car is still moving or it still ignites but remember you felt a strange noise from either the exhaust or the gearbox but we keep managing it until the car dies in our hand.
We shouldn't do that to our bodies,we only have one body,not two so lets take good care of it.
Know your body like you know your name.
