I partially agree with the author's statement because ,to become acquaint with the modern day convenience and luxury also require an accomplished brain .but at same time they provide an easy mean which make an individual to skip his natural physical and mental efforts.

for example these days electronic gadget computer ,mobiles ,Internet services all make our work faster .Be it banking ,ticket booking ,getting a service in a remote area,social networking ,or getting knowledge and information about particular topic all can be done in a jiffy .
To well verse with computer jargon and to use it for good purpose requires a good aptitude and logical brain . I would rather categories these things as essential luxuries of modern times which make a person more efficient in executing his task and daily routine life .

But their use beyond a certain extent make a person quite dependable on these gadgets. For example students who carried out his math’s assignment and if he uses computer or calculator to do quickly his home work .He will loose his inherent capabilities ,of logic, aptitude and reasoning .After all human brain is ,who has designed the computer and becoming slave to the same machine is really dangerous to an individual's natural innovative brain capabilities.These days school student carry out their assignments on computer tools so what they loosing is their own hand writing skill ,which is in true sense an art. Even in artistic areas computers use has increased a lot ,and an individuals natural and unique creative power is taking back seat .

On the other hand having a luxury car , a posh mansion to live ,splurging money for enjoyment like clubs ,parties, discothèques all are part of superfluous requirements of basic living.These luxuries make a person ,hedonistic .A person probably having a bicycle will carry out his daily chores by using his bicycle in near by area may be 3-5 kilometers area on the contrary a person who is having a car may become addict to his facility and even to move a mile he need always a car.

So what i bring out from this discussion is luxuries and convenience of contemporary time should be used as companion of man kind.So where ever possible human being should execute his task himself and where ever it is beyond human capabilities ,and time is really a constraint these gadgets should come in picture .Then in true sense a person will be a strong and independent individual ,where he is master of his gadgets and facilities rather than a gradually diminishing slave.
