Individually....

"" Bridges are above to the earth having not direct gravitational force,, so if we move along same way we can be feel high pressure....

"" Same pattern of running and walking get habitual to our regular way but while go on bridges regular area gets change so we should also change the pattern...

"" Same pattern can creates a heavy pressure and extra normal internal activities also ....

Socially .....

Hey mate ^_^

=======
Answer:
=======

=> Bridges are important structures that help to connect two parts of the land.

=> They provide passage for crossing natural barriers, such as rivers, lakes etc.  

=> At a certain point, the bridge would start oscillating to the same rhythm.

=> This oscillation would reach a maximum peak when the bridge can no longer sustain its own strength and hence collapses.
