There is definitely some confusion going on here. Netaji was born on Jan 23, 1897. Simple calcuation will reveal that if Netaji were alive today his age would be around 110 years. Whereas the age of this man who died is believed to be around 125 years.
We have two facts that are mutually irreconcilable.
So either the age of the man is in error of 15 years or the man's claim is false. It is anybody's guess that this is just one more case of a man claiming to be Netaji and acquire fame after death.
