[General] I'm Immortal. Can I still retire?

Say I stopped aging around age 35. Worked for 30+ years at a company without aging and am now 65. Since I've put in the time, can I still collect retirement and social security indefinitely until these things no longer exist? Asking for a friend...

It's likely that you'll eventually be discovered and purged from the system as a bureaucratic mistake. Since you continued cashing checks well after a reasonable lifespan the IRS will likely launch a fraud investigation. Now you're not in a great place. Since you look 35 they'll probably assume you're your son or grandson that continued to cash the checks after the original applicant died. 

You can now either reveal (and prove) you're immortal and sign up for all the MK Ultra experiments the government wants to do on you, or you can plead guilty, do your several years in a white collar prison, and then start a new life at 35 when you get out.
