Life can be compared to a computer, It takes some to start and generate sense just like computer loads its window components. A human starts acquiring knowledge just like softweres are loaded on our computer. Knowledge becomes much advanced like updating softweres we also update our knowledge. We need a system care also for our life who will keep us safe and care of(our parents). some times our life get infected by viruses and malwares of illness it is then when we guidance which is our antivirus. It is our responsibility to take care of our lifely computer and clean it everyday and running antivirus scan every fixed interval of time. The difference is if a computer got damaged it can be replaced by new one but once our life got damaged it's impossible to come back to a good life.
