Question explored with the scientific record
what are the recovery numbers and potential for Long covid in a 74 year old healthy male, numners worlwide
The short version: the evidence retrieved does not contain a single study that answers your question about a healthy 74-year-old male specifically, and the gap itself is the finding.
The evidence you got is a scattered collection. One Thai hospital cohort found about 40% of adults had long COVID symptoms, but the median age was 58 and the range went up to 74, so it includes people like you but does not report results for that age group separately [1]. A Turkish study of cardiopulmonary fitness after COVID included people up to age 74 but had a mean age of 43 and did not report recovery rates for older adults [2]. A Spanish study of hospitalized survivors found 58.7% with cognitive impairment at two months, but the population was hospitalized and the age range was 22-81, again without an age-stratified recovery number [3]. None of these studies compare vaccinated to unvaccinated older adults, and none track recovery over time in a 74-year-old healthy male.
What is missing is the most important comparison: a study that follows vaccinated versus unvaccinated healthy older adults for long COVID recovery. The evidence here does not contain it. The studies that exist are small, single-center, and do not report the outcome you need. The burden of proof is on the people asking you to accept an intervention, and the evidence for recovery numbers in your exact situation simply has not been produced.
My call: the retrieved evidence does not answer your question. The gap is real and should matter to you. Confidence: not clear, because the studies that would answer it were never done or were not retrieved.
