Southern Railways — Senior Citizen's birth booking

Address:

Dakshina Kannada, Karnataka

Hello,
I am a senior citizen, i had booked a ticket to my hometown recently online, after filling all the details,when i saw the final sheet ,i had got the upper birth,being a senior citizen its very difficult for us to occupy the upper birth.This has happened many times.
There should be some provision for Senior citizens so that we get only lower birth else the ticket should not be booked.
Its my humble request on behalf of all Senior Citizens.
