Is the life span of humans increasing or decreasing?
Do you feel that the life span of humans has increased due to better health care? Or is it on the vane due to activities which are keeping people unfit?
The average life span of a human is said to be 80 years. But today, is the life span of human increasing or decreasing? In earlier days, people stayed fit and active. People had a lot of physical tasks to do and people had to walk or cycle for longer distances and that way people stayed healthier. But there was no advancement of medicinal field and hence many diseases would go unnoticed or untreated and people had to suffer or take the last breath.
But today, people have no physical activity. Even for a shorter distance, people prefer a vehicle over walking and most of the work is automated. We humans are getting lazier and many health conditions are associated but with improvement in medicines most of the diseases are curable or can be controlled.
So my question is, life span earlier was more as people were active and healthy or is it more now with improvement in medicinal field?
