It is currently thought that the maximum life span of about 117 years. Obviously, most of us do not live that long. Why? Part of the answer is that we eat all of the time, and move around all of the time, and therefore must keep breathing; thus, we are vulnerable to the consequences of oxygen permeating our body.

Can humans live for 200 years?

These are natural changes that occur while aging. They cannot be stopped but it is possible to slow the rate of these processes. This can be done by changing one's lifestyle (diet, exercise, etc). The science of aging is not yet fully understood; therefore, it is difficult to determine an absolute limit of 200 years.

How can we achieve immortality?

By preventing cells from reaching senescence one can achieve biological immortality; telomeres, a "cap" at the end of DNA, are thought to be the cause of cell aging. Every time a cell divides the telomere becomes a bit shorter; when it is finally worn down, the cell is unable to split and dies.
