Come on guys, The Basic message is keep fit and stay safe, Take all the BS out of your posting and that is what we get.
As one of you said combustion is the same in all parts of the world, Some understand it and Some don't, The danger is still there, Extra stresses on the body, heightened chances of Heart attack or other injuries.
As for wearing seatbelts look at the dash or visor in your truck, read the safety briefs, We are required to wear seatbelts by law and still some don't. Friendly reminder don't hurt.
Now you can have a go at me.
