That you're 35, or 45, or even 55 - ages that have almost the same level of (very low) risk to develop many of conditions we think of as "diseases of the elderly" - will be irrelevant.
You'll need a reason, and "getting older" over 8 or 10 years will be right there waiting for you.
I know for a fact that doctors are *already* telling people in their late 30s that their rheumatoid arthritis, new-onset T1 diabetes, cognitive deficits, and MCAS/alcohol intolerance are just "aging"
