If physical fitness is a MUST, then some of us are without hope.
Age and diseases take a toll that prevents many of the elderly over 70 from being fit. Accordingly, we must do what we can under the circumstances, but for many of us fighting off an attacker for more than a few seconds is out of the question.
Such problems come upon everyone if you live long enough. Fortunately, with good judgment the odds of attacks are very small. I can attest to that and so can those I know.
Yes, it can happen to anyone anywhere, but it does not except in very rare instances.
Ecclesiastes 12:13 *¶Let us hear the conclusion of the whole matter: Fear God, and keep his commandments: for this is the whole duty of man.
14 *For God shall bring every work into judgment, with every secret thing, whether it be good, or whether it be evil.
