You're probably right, Matt, but it's surely part of the responsibility of anyone who regards themselves as part of Steve's team to be mindful of his health, and to provide some degree of oversight which he himself may not be fully able to do. The impression I have, which may well be wrong, is that Hoppo and Idai have taken on the roles of coach, cheerleader and nutritionist, and therefore they must also take responsibility for advising Steve in his own interest, and not the interest of the task - which is now impossible anyway.
