Well it looks as though that ripple of volunteerism has spread throughout France as the national blood doner service has seen increased numbers of people coming to its collections.
The Sud Ouest website reports that at one event over the weekend in the Lot-et-Garonne 111 people turned up, way above the 55 or so expected.
On Wednesday morning in my local village, Villefranche du Périgord, there were around a dozen people filling out forms, seeing the doctor, in the process of donating blood or enjoying a drink and a biscuit afterwards.
Two more people dropped in as I chatted to a nurse, and the collection from the village will go on to Bordeaux where it will be used or if necessary transferred around the country.
The national blood donor association, L’Etablissement Français du Sang, said that on Saturday, 14 November, the day after the terrorist attacks, nearly 10,000 people turned up at centres across France to donate blood.
The number of people donating blood in Paris was three times as many as normal, while nationally there were twice as many people.
Unfortunately British people are not able to volunteer and donate blood due to fears over Creutzfeldt-Jakob disease, or mad cow disease.
The restrictions mean that if you spent a year or more in the UK between 1980 and 1996 then you are prohibited from donating.
If people are able to donate blood then they must weigh at least 50 kg and be aged between 18 and 70, with the actual process of giving blood taking 10 minutes and with a minimum of 400 ml being withdrawn.
