Have you ever wondered, why Ronaldo did not have a single tattoo on his body?

Cristiano Ronaldo does not have a single tattoo on his body as he is an avid blood and bone marrow donor.

While having or getting a tattoo does not strictly prohibit one from donating blood or bone marrow, restrictions are advised and observed by blood donation facilitators.

The Red Cross advises that individuals should wait 12 months before giving blood if they have just had a tattoo applied in a state where tattoo studios are not regulated.

Blood donation organizations in the United Kingdom generally advise potential donors to wait at least four months after getting a tattoo before giving blood.

The former Real Madrid star often uses his social media platforms, such as Instagram and Twitter, to promote the cause of donating blood.

Cristiano Ronaldo is the biggest star of social media platform Instagram.
