There can't be many people that have never known anyone that has died from cancer.
There will be others that are lucky enough to know someone that has recovered from cancer.
There will be others that have survived the illness themselves.
Days like this are to bring awareness to the world.
A wristband won't help find a cure but it will raise money to fund research into fighting and eradicating this some time in the future. It will no doubt be too late for people of my generation, indeed it may take several generations before the battle is won.
The ball is in our court.
