As an inveterate walker I am bound to forget something -- John Wright Use your imagination Marvin! Life's bad enough as it is - why invent any more of it.

That is true, and the same thing applies to walking, and even standing. >Helmet testing is done as a drop test, and your head can >some reason.

Let me give a referee's report on your submission: What the drop test demonstrates is that someone can drop a brick on your head from four times further above it, but the form of impact it tests and that which is typical for cyclists coming off are sufficiently different that it may not carry over. Please provide some evidence that the results do carry over, and resubmit. Regards, Nick Maclaren. |
