from my thought, laziness is you put off things you need to do. This might sound somewhat similar to distraction, but the difference lies in the fact that procrastination is an internal factor. It comes from within your mind and can be caused by various factors like fearing a negative outcome, or not being able to find a starting point.
Again today’s lifestyle drives people to taking quick snacks and take-away foods that overtime can lead to us feeling rundown, or being overweight. These areas like; poor diet, lack of the right vitamins and minerals, and/or insufficient exercise leave you with little energy that also contributes to your general feeling of laziness. For example, if you have an unhealthy diet that is laden with junk food and sugary snacks/drinks that lead to hormone or insulin spikes, then you will probably feel lazy because of them.
