Yes.
I have annual MOT and do functional fitness or cardio every day for at least 30 minutes , eat a varied and healthy diet, don’t drink excessively, and drive a Volvo
I also monitor my fitness levels regularly.
We only get one body and I want it to function well into old age. We can’t guarantee what the future holds, but that is no reason to neglect our minds and bodies.
We are told to live ourselves and surely one of the foundations of living ourselves is wanting to e healthy?
Or do you mean ‘are you a hypochondriac who assessed every ache and pain for cancer symptoms’? In which case the answer is no.
