… we have certain software facilities available in our life…

  1. Shortcuts like Ctrl+z, Ctrl+x, Ctrl+Alt+Del
  2. Modes like Hibernate, Shutdown, Refresh
  3. Facilities like record, replay, Undo
  4. Clearing the cache and in-built firewall for external allusions.

Though life (rather time) goes always in forward direction, our thoughts and ideas travel in backward direction sometimes.

PS: On a lighter note, I and my friend used to feel bad for the lack of zoom facility for the eyes. It would have made the bird-watching sessions much more brighter πŸ˜‰
