This is a good idea on a number of levels.
Service histories come in all sorts; military, scholastic, vehicle, appliance, etc. I even met a person who kept a service history for their clothing – to see when it needed cleaning or repair. That might have been a little obsessive, but all the other sorts are valuable information:
a. The military service of anyone – if you can get legitimate access to it – can indicate a great deal about their character. Not everyone is Audie Murphy, but the basic behaviour of the serviceman or woman is noted all through their period in the armed force, and you can pick up the general tone. If they have spent more time in the brig than on the parade ground, they may not be the best choice for a an executive position…
b. School records are generally lists of courses taken – passed or failed. Again, major achievements and crimes are noted, but it’s as well to remember that students are young people and often subject to being jackasses.
c. Medical histories are very important as they can let you know what has happened and then you can speculate about what might be in the future. They can be the most closely guarded of the data lists, and for good reason.
d. Vehicle service history is valuable on two levels; it lets you know when the next service is due – and what will need to be replaced – and tells if the owner of the car or truck has actually done the previous servicing properly. This can be a big money question when trade-in time comes around.
e. Nearly at an end, Folks. Appliance service records are rarer….though they are kept by repair shops and service personnel who call at your home. They are as valuable as the car ones, and sometimes more so because they can remind you how often a piece of goods has busted and suggest when you should stop servicing and replace it.
I noted this earlier in the week when the radio went bad again. The hi fi shop could tell me how often it went bad before and that prompted me to remember the actual age of the set. The fact that our pandemic has reduced availability of spare parts and service persons also played a part in my decision to leave the dud on the counter for the shop to pick apart and to take a new one home. It actually was cheaper.
