I think it's the nature of being a labourer, really. Your body is the machine, energy has to move through it by way of forces. Our spines are just not that great at holding up under the forces. Sorry to hear about your wife's situation, too. If she has an office job a nice chair goes such a long way. I got a HM Embody and can say that it improved my ability to work, since there's a lot less pain now.
