Question

can you please answer these

Answer 1

computers- they have made our life more easy and enjoyable. If you are having a computer with an internet facility , there lies a world where you can gain knowledge freely .. But today's children are taking the computers in a wrong way. They are sitting before the computer for day and night like some kinda addicted one and is keeping theirselves out from the real world. This is totally a challenging problem faced by the present generation today. Everyone are getting surrounded near the computer. 
Actually this will affect out health badly. When we stare on the screens which produces various amounts of light rays , our eye sight will get affected in a bad way. sitting before the screen with the shoulders straight will cause back pain. This is the reason why almost everyone working in IT field are having lenses and shoulder pain. Because all they do is sit before the computer from morning to evening. 
The results will be worse in children. Because children have tender body. They are meant to make it strong by playing outdoor games. But, today hardly some guys are interested in playing outdoors under the sun. The interesting fact is that even their parents dont wish their children to go out and play. They dont wanna see their children getting hurt. 
This mentality should be changed. Children to grow watching the environment and the nature and not the computer games. They should live lively with good health . This will only make their childhood worth  enough to remember later, 

2) walking- it is considered as a show of one's poor character . Today everyone think that why we should walk if we are having some good vehicle. They think that walking is considered as a job done my minor section of the society who cant afford a travel. But the fact is that , walking is what keeps us healthy. It will only improve our vital functions making us improve our daily life. It will give us a chance to see and enjoy the nature . 
Delhi was rated as the polluted city in the world in the last rating. But now , its not even in the top 10 in the latest ratings. Its because of the odd-even rule brought in by the government which decreased the vehicle usage. This decreased the pollution . People started walking and depending on public transport for travel purpose. This made a massive amount of changes in the pollution level. 
Walking is only a boon. Only the ones who lack the ability to walk will understand that. But the ones, who save their feet from walking are actually keeping them selves away from a chance- a beautiful chance to be a part of the nature, a chance to see nature
