Mrs Lopez blogged from the seaside town of Muxia, where she was born in 1911, or from the farmhouse in Galicia belonging to her grandson, Daniel.
Her blog, at amis95.blogspot.com, became a global hit, notching up more than 1.5 million visits. As her fame spread, Mrs Lopez became an unlikely campaigner for digital rights for older people, and even took tea with the Jose Luis Rodriguez Zapatero, the Spanish Prime Minister.
I've got 35 years to go to equal Mrs Lopez's record. Will I make it - only time will tell. Stick with me to find out!
