The human body would always get Ill from time to time.

Yeah, that's what I am saying. Cannot be avoided.

you have to know that a lot of people engage in unhealthy and dirty risky lifestyles that will always make it easy to fall Ill.

What are you going to do about it? That happened, happens and will happen.
Also, someone could easily say that your lifestyle is a dirty and risky one, in fact, people say that about smoking or consuming weed. Are they correct about you? If someone catches you right in that one act you might have overdone and abused it, they might judge you just because of that. They might not see the other side and so you cannot put your own mind-spirit into another humans head and direct from there what one shall think and how one shall move ones arms and legs. I find that a funny imagination, that's why I used it :)

A family member of mine abused alcohol for almost all his life. So, judges popped up everywhere. But I think he had a reason to drink and I cannot judge him, only leave him alone if it's too much for me to be with him. I decided doing that. He came out "clean" one day, this is now 15 years ago. Being a judge towards other people who seem to have caught a "bad habit", I find unnecessary. You can never tell, if someone will be successful to change a habit or not until he or she is no more. But as long as someone stays alive, it's way too soon to judge. Even then, judging is of no help. What seems to be bad for you, might be needed by another one as far as it's needed. Maybe for a while, maybe for the rest of ones life.
