Shorter Attention Span

A shorter attention span almost always denotes the lack of a persons ability to concentrate - which is necessary in most tasks today. It is also linked to forgetfulness and overall means that we are a lot less productive then we ever were or could be. Irregardless of decreasing attention span, the work hours have not decreased so one is expected to stay focused through out this time period. Shorter attention span most importantly means that we have a hard time retaining information which is a major impediment to our learning process.
The ability of a person to concentrate significantly affects his productivity and his ability to go through with a task. People often need to tunnel vision or zone into a certain task to get to the crux of it.
As a result, we need to keep looking for the same things over and over again, which would not be a problem in any usual scenario, but in a task that has a time constraint, one would most likely fail to meet their deadline. This is more evident than ever in an example we all have faced at least once - when queuing to pay for an airline ticket or any place that requires you to do queue for payment, the receptionist keeps asking of pertinent details and from a brief lapse of concentration fails to remember what was previously said, often requiring one to repeat the same thing over and over again.
The decrease in attention span has not changed anything regarding the work schedule of regular people. The lack of change in work hours would mean people would need to keep up the same level of productivity for hours at once. This is not possible as people generally tend to be extremely productive earlier in the day and taper off during evening. This makes matter worse for people with shorter attention span as they wouldn't be as focused during their productive
