for example for the set of all real numbers greater than zero and less than one the numbers one and zero are limit points since one can pick a number from the set arbitrarily close to one or zero even though one and zero are not themselves in the set
Valor Service Dogs. Valor Service Dogs is a 501(c)(3) tax-exempt nonprofit organization that helps post-9/11 wounded veterans regain their independence, return to civilian life, and maintain their warrior ethos. We make this happen by training and placing mobility assistance and PTSD service dogs with our veterans.
It follows that making the right choice (which may vary, of course, in the eyes of others) will determine whether or not discretion, in a given instance, is the better part of valor. In saving one or the other from drowning, in the above example, it is clear that both acts, saving the dog or the human, are valorous.
