Hey Guys,
I've just come to know that in fifty thousand people you can find one person whose heart is a reflection of mirror, which means that his heart is at his right instead of his left side. just wana know if this true and why is that so? :-\

It is true, and these people are completely mirrored, not only their heart.
The condition is called Situs Inversus.

Also, when people discover they have Situs Inversus, they must always carry note in their wallet close to their ID in case they would ever need emergency aid.

Situs inversus is generally an autosomal recessive genetic condition, although it can be X-linked or found in identical "mirror" twins.
