martial arts ,specially chinese and japanees styles are not only a fighting training its also a way of life. a way that shows you you should keep both ready to life well : the strong soul and strong body, every kung fu fighter almost know this .so i think most of ppl who train martial arts (every one who understands what really martial arts means) will choose to keep training anyway .
some people said that street fights are usually by gun fires or like this; if it be hard to defend your self in a situation does it means you should not defend yourself then? its up to u guys to answer .

its in persian language :
goftand yaft minashavad gashteim ma \\ goft anke yaft minashavad anam arezoost

which is translated to English here:
they say its never gonna get found we looked for it already
\\i answered what is never found is what i wished to find

One good example of this might be the worldwide popularity of Tai Chi. It's straight up traditional kung fu, but people of all ages train in it for a wide range of reasons that have nothing to do with fighting. Still, speed it up and you could repel an attacker. Maybe even not speeding it up if you were proficient enough.
