I know someone who doesn't believe in medical checkups; they feel because they look healthy, it means all is well within them.
I don't joke with my health. Whenever I feel something different inside of me, I don't hesitate but run to the clinic for medical checkups.
There are a lot of people like that . Some will even tell you that that those who go to the clinic for a check are looking for sickness for themselves.
That's a very good habit you've got there, I wish to cultivate that too
