Well, of all the modes of transport, sometimes I feel that Walking, is so much convenient ! Truly, the root of the various modes of transport is particularly to reduce the human effort. (And that, actually, is the definition of "Machines"). But the people who invented all these stuffs, didn't actually rely on the fact, the human sect would be exploding in numbers, within a couple of decades. And apparently, it has and has been making the exact use of mechanical modes of transport, vulnerable. With the increasing number of vehicles on the road, we might have at many times felt that, "Ah, I will walk till then, rather get cuddled in this traffic !". Well, that same statement applies to me ! I've often taken the pedastrian route to particular places, though I could have chosen other means. Because that has often turned out to be more efficient ! Unless, the route amounts to a number of kilometres ! And ofcourse, it helps me stay healthy as well. :)
