This was in interesting video with important safety information. Because I am interested in the value of used helmets I did a bit more reading and found the articles below to be informative (my brief conclusions after this little bit of research in brackets). One reason that I did a little more reading is because I have been hesitant to provide and encourage the use of second hand helmets at the bike repair sessions at Our Place. In the future, I will not be so hesitant since I conclude that wearing an old helmet is safe and dramatically better than riding without a helmet. Mikael ps. Happy to learn more about this. Additional peer reviewed references are welcome. 1a. MIPS (MIPS technology significantly reduces the rotational forces that can lead to concussion) Hoshizaki, T., Post, A.M., Zerpa, C.E. et al.

MIPS continued (the impact of MIPS on rotational forces is reduced in models that incorporate a more realistic head ie. One with a scalp that can slide against the skull) Hoshizaki, T., Post, A.M., Zerpa, C.E. et al.
