Improvisation involves adapting whatever resources one has available to solve an unanticipated problem. Being a jack of all trades may be very personally useful, but it does not seem to pay well. Developing highly skilled but uncommon abilities to respond to important & highly demanded needs is remunerative. In the process of developing the latter, one also can develop skills which can carry over into diverse fields, but to make them truly usable & useful, one needs exposure to a broad variety of problems and solutions. In the process of highly developing those narrow skills, one can develop a very sound foundation upon which to base the more generalized, diverse skills & knowledge which are necessary to develop an adaptive, problem-solving mentality.<br><br>Thus, studying survival situations, & developing the material & human resources necessary to meet them is useful when survival problems do occur even though they may differ from the ones previously considered. The human mind & body are wonderfully versatile. People will try to respond to new problems using old, adapted, or new approaches depending on what they deem most appropriate. Some will succeed. The more knowledge, skill, ability, & material resources they have available, the greater the chance of success. <br><br>In short, what we are doing is worthwhile. But it would probably also be valuable to explore different scenarios.<br><br>Do we need a another (3rd) forum to explore diverse survival problems?<br><br>John
