You are talking opposite things in same line. Wasting energetic years of one’s life vs putting an age limit.
Now imagine what if 32 age limit is not there , the pool just got infinite and your chances of selection will be lower.
So benefit on putting an age limit is two fold getting younger workforce in to govt , also there is cap to ppl to not try like infinite times
Talking about wasting energetic years of one’s life , I don’t see it as a waste it is one’s choice to prepare and get in to the services. There is no compulsion here. Too each there own. It’s a good thing ppl try hard things it may seem waste at the moment but will be enriched and cherished long term
Personally I feel if you are preparing from college etc 2 years is good time gauge where you stand and take an extra 1 more additional chance with the job etc. If you are newbie 3 would be good.
My thoughts on this exam , it should be limited to 4 chances for all unless educated in govt schools like say 6 years out of 10 (not including college) irrespective of caste, they should be given more chances say 6. Age limit for both should be 28. No more extensions.
If one really wants to do service there are many ways! Cheers
