Best Paediatric Orthopedecian in Bangalore | Dr. Jayanth S Sampath A lot has been said about the heavy school bag – but none of it has lifted a kilo from the monstrous load our children carry every day. For a weeklong backpacking trip in the Himalayas – which requires at least a month’s preparation and specialised clothing and equipment for roughing it out in the wilderness – one is asked to carry a rucksack that weighs no more than 10 kgs. Most domestic fights keep the hand baggage limit at 7 kg. But, somehow, it is okay for a 12-year-old to carry on his or her back, a bag that weighs 11 kgs – just for a day’s study at survey of the kind of bags children carry to and from school, daily.
