Order a new one when one catches my eye, Mission helmet is still my go to. Got a carbon one last year and love it 

I get them from Indonesia. They make brp ones there too. I have about 10 good ones 👌. 

Helmets to me are like an old pair of jeans. New ones suck.  I only buy a new helmet if my visor fails and I can no longer get a new one for it.  The balaclava I wear under it is harder to replace. A few years ago I needed a new balaclava and ended up with about 20 of them before I found "the one".

Yeah too much is no good either. I have farm bearings in my feed lines. I took weight off ends by mounting hoppers on ceiling. Now the bearings last forever. So load in a trailer would affect how long they last too, especially uneven loads, if person always loaded that way.  I no longer add any grease to my bearings I just leave them and back to shop it goes in 5 years. Never had a bearing failure.
