Is your head in a Fog?

It is funny how people interpret the fog. At times it is perceived as confusing. Other times one realizes that he can not see well in a fog. Both of these observations are true.

Today, my friend and teacher, talked about how it was unwise to exercise in the fog. Since she is from China, the people there are plagued with pollution. At times the fog they experience is more smog than fog. Fog by its very nature is water driplets expanded over a large area. But when it is mixed with the pollution, people rightly so interpret that as being harmful to the body. It goes into the lung and forms water pockets in the lung and thereby causes breathing problems.

So without proper experiments, this problem can not be conclusive. However, the health of the body is important, so excercise with caution and understand the consequences.
