When should I replace my bicycle helmet?

Replace your helmet after a bicycle accident. Even though it may not look damaged, it might be. Many manufacturers have a crash-protection guarantee and will replace a helmet for free if you are in a crash.

Helmets should be treated carefully, and not be exposed to extremes of hot or cold, which can damage them. Consider replacing your helmet every five years, as helmets can begin to deteriorate internally with time and use. The quality of helmets has improved so much in the last ten years that the helmets manufactured five years from now will probably provide even better protection.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
