You can push it back to 1944 if you’re in the US, the war wouldn’t have impacted you much. You could even push it back to 1940, but there may be some depression era nutrition issues.
That bumps 2001 up to 57. Honestly go for a few more years and retire before '08 and die in 2019 before covid at age 75
Being 75 puts you in the choking to death from covid range, no fun.
