Now for something serious.

I have a form of Parkinsons. In my situation it is the trembling and sometimes lack of equilibrium. I am building a 318 for my grandson. Somedays I can get one bolts or one nut installed and I am done for the day. I had o get a new torque wrench that was not "click type" because somewhere in trying to apply steady even pull on the wrench the trembling will start and the wrench click and I am nowhere near needed torque or way the hell over. May take me a year but I will get it done.
