The world is changing fast and if we don't stay focused on the road ahead, resisting the distractions that, while tempting, are, well, distracting, then we increase the chances of a crash.

Most runners have at least one story about a race whenthey felt so great during the first few miles that they ran ahead ofpace, only to crash and burn during the final miles.

It is sothin that a smoke particle, fingerprint, dust, or human hair could cause what is known as ahead crash.
