The average quality of human health is going to be decreased in coming time than in present. I agree to a great extent that people's health will be affected in near times. Moreover, they are more likely to be ailed with serious diseases.
Due to decline in intrest for morning and evening walks, and heavy exercises, a large chunk of aur society is having severe health issues. This habit is taking them toward the health problems, which are not dignosed until last stage. Ergo, resulting in low quality health as well as minimizing average age of population for future.
In addition to this, increased number of sitting jobs are one of the factors which is adding to low quality standard health. For an example, earlier there were plethora of field jobs which kept human body in movement every time, resulting in healthy lifestyle. That body movement is now left in fingers running over keyboards and mobile screens.
On the flip side, some individuals are aware of problems surfacing in human body. They have had already changed their diet to diminish the negative effect on healthy living.
To sum up, exercising is must for healthy body, along with proper diet. Otherwise, average human health will be lowered in future than present.
