Here is what Mark has to say... "People I have worked with are entitled to their privacy as part of the agreement that we make before we agree to work together.

However, a few of the many people that I have worked with have agreed to tell you some of what they were going through and, in contrast, how they live now.

This includes the quality of life that they enjoy now and some of the differences they experience in how they think, feel and behave.

They also, if it is the case, describe some of the shifts in attitude and behaviour of the people around them. Often changing ourselves is the best way of changing the dynamics of our relationships with others.

I for one appreciate them sharing their stories, giving you the opportunity to make a more informed decision for yourself.
