Life is full of unforeseen events. Events that usually break the normality of things, the status quo, balance. Sometimes these events place us in extreme situations, and sometimes we also owe the survival to another being, to another body, to another "outsider."

Las Tunas, Cuba.- Seen this way, many people owe being "safe and sound" to Joaquín Antonio Pacheco Pantoja. But this 57-year-old man does not stop to think that his, is an act of heroism. He does not notice the magnificence. While he extends his arm with generosity, he does not need greater philosophies.

"I had about 200 blood donations. Later I was called to make platelet contributions for the needs of the country for some patients. I will continue contributing as long as I am healthy; at any time they come to look for me, there I go. I do it with love, without expecting anything in return. For me it is a pleasure and a pride," he says.

Pacheco, as friends and acquaintances call him, is a signal and communications repairman on the Las Tunas railway service; also a plumber, electrician and willing man for whatever it takes.

Can the unforeseen connect us to others, without a name, without a face ...; hold us in an invisible bond?

"As long as I have blood to donate, I'll be there," says Ariam José Herrera Vega. And his blood, AB positive, runs through other veins, as do his platelets, which he has already donated on several occasions; although he remembers more when he benefited a baby in a moment of those in which other hearts must have throbbed quickly and painfully. Ariam felt satisfaction in doing something good and useful.

"It motivates me to save a life and helps someone who needs it," he summarizes. Ariam does not abound much, speaks little, but expresses what is necessary. Either as a worker, until recently the Electric Company, or as an entrepreneur in his own business; you can count on him to donate blood and life.

According to the World Health Organization (WHO), nine out of 10 people need, at some point in their existence, to be transfused even when such action is not carried out.

In situations of fragility, risk, fear, tension ... at the limits, there is always someone or many to thank, even without having a face or a name. it had been said that "the slight flutter of a butterfly's wings can be felt on the other side of the world" or that an invisible red thread unites us ... We, humans, say so many things to explain to us the universe and its endless concatenations. I say that there are people who save and love.
