Though a baby and an old person are very different in point of age and experience, they are much similar in respect of physical ability, mental strength and economic condition. A baby is physically immature and depends on the adults around him/her for physical movement. Similarly, an old person may be very weak and depend on others for his/her movement. Again, a baby possesses a little mental strength and can hardly exercise it. Likewise, an old person lacks mental strength and can hardly cope with mental pressure. Finally, a baby has to depend on his/her parents for all financial support. An old person, too, often depends, on. his/her sons and daughters for economic assistance. Thus, a baby and an old person have much in common, though the former has just come to this world and the latter is about to pass away.
