Money and injury

I have noticed a connection between money and injury. The lack of or the unwillingness to spend money and finances I think can predispose one to injury.  This is due to a number of factors,i) the stress of not having money ii) overworking iii) not using the right tools and equipment.  In terms of practical examples what this means is having your car and/or bicycle regularly serviced, with a computer investing in good speech recognition software – if you decided to use this, a good mouse. Unfortunately it may also mean spending money on getting the right diagnosis to determine whether you have an injury and what it is.
