Knock the resume to no more than 15 years experience, take off older technologies and techniques, and understate your accomplishments.
I have seen contractors walk off the job after a week when someone else offers them a higher rate. The ‘no strings attached’ stuff works both ways.
Good luck trying to hide your age, degrees, work history. Most of it is available with a quick google search. One suggestion is to say you retired but would like to come back into the workforce at a lower level than when you left. I don’t know if that works.
