Talking about helmets i lost a very dear friend just because he was wearing helmet but he did not use the helmet belt to secure it.
He was on 9th ave when he fell into drainage when a suzuki van hit him. It was a minor accident he stood up called his bro that he is fine but than he lost consciousness he had no physical injury but bleeding in his brain.
He was in coma for around 2 weeks, poor guy got love married to a nice family girl week ago with all world against them due to his poor background and girl with kinda rich, Rented his own one bed room very cute apartment and this happens. Never in my life i will forget the screams of that girl thousands came in his janaza and never in my or my father's life we attended such huge gathering.
Not the one incident i saw I have seen a man killed infront of my eyes on express way when he fell down and hit big cat eye on road and his cheap helmet brust open I saw his brain on road.
Most of us buy helmets just to avoid chalans than we drive motorbikes in first lane. Your life is very important for your loved ones always prefer best quality safety product available.
