What is Survival?...is it depends on will powe?r....or on the available resources?
If you have the will to survive, you will survive and not just live. You will be able to return to society knowing you, and you alone, keep yourself alive. You will know that you kept yourself alive where many others would have simply given up..and died. You will be proud of the fact you didn't just live, or even die, you were truly a survivor
Survival mustn't be confused with camping in the wilderness, in winter on a mountain armed with a tent, sleeping bag, cooking equipment and food - this is not survival. Even extreme backpackers , people who compete in events such as mountain marathons, who plan everything they have to carry, down to the last gramme, will still be warm at night and have enough food to last their expedition - this is not survival.
In these examples, the people in question have planned for their trips, have warm clothing, adequate cover from the elements, enough food etc, also they are most likely well practised at what they do and probably do not go alone. Another person, wearing normal day-to-day clothes, with no camping experience or specialised equipment placed in a similar environment as the above examples, would struggle to cope - this IS survival.
Who is most likely to survive?
If it is about our species, then we do not have much choice since we are just by-products of experiments which Nature keeps on doing
On individual level it is the Divine grace, on which all survivals depend upon. (That does not mean that will power as well as availability of resources are not important)
