My father in law has been suffering with this disorder Myasthenia Gravis for over 40 years. Anybody who knows me knows i love walking, so I thought walking for this charity would raise awareness of this debilitating condition. There are approximately 67 million people in the UK and approximately 20 thousand suffering with Myasthenia . Basically 3 in every 10,000 people have this condition. Elaine Simmons
