To me the definition of heath is a state of being for the body where it is able to function unimpeded at optimum levels and without adverse effects. Then illness is the physical manifestation that can arise from a sickness or injury, like if you have the flu your illness is presented by a fever and vomiting.
To me cancer is a illness, because the tumor is the physical manifestation brought on by the unimpeded replication of cells that occurs when there is a defect in a cells genetic code that leaves it with the reproduction switch flipped on. Even though most people lable cancer as the disease it is really the byproduct of an underlaying problem. We see the tumor on the CAT scan and people tend to see that as the problem because they can’t see the individual cells that are reproducing out of control. So in an atempt to rationalize something they don’t completely understand they label the tumor as the problem not the result of the underlaying condition.
This was a tricky one for me but old age by my own definition is actually an illness which is very weird for me to think of it that way. Because in my own head old age is normal and we tend to think of an illness as something that is out of place. Something that is not natural and that needs to be corrected. So this revelation actually made me think of illness in a new light. Because by my own definition old age is a physical manifestation of a long life of veing exposed to various things that can cause small changes in our bodies. For instance in a previous class I took they looked at identical twins and there genetic information. At a young age it was nearly identical, but 40 years later it was as if they were almost two different people. There genetic sequence was still the same, but a new field of study called epi genetics which studies the switching on of different genes. Shows that over time even people with the same DNA change over time when exposed to different things.
