Don't follow the herd

In the wildlife animals move together as a group and herding behaviour is not uncommon. Humans are not that different and can build up group momentum following just one or two leaders. As it turns out this herd mentality and behaviour of humans can be observed in all walks of life. Every hour of the day we are bombarded by constant need to make decisions and most of the time these decisions are affected by what those around us are doing.
