Hi Harish,
Yes, I believe in certain countries there is no age limit for medical entrances such as United States. You can give the MCAT exam in the US at any age, and join MBBS.
As per JIPMER, there is no upper age limit you can appear for them any time.
However for AIIMS upper age limit is 35 years.
Here is a link if you are interested in doing your college from overseas (USA):

If you are interested in doing MBBS from Russia, then unfortunately you are not eligible to sit for NEET examination..and that score is used to get admission at Russian medical colleges. You are still eligible to give JIPMER! Study hard, it's never too late for anything !:)
Hope this helps! Good luck! All the best !
