I always like to use William Shatner as an example, even though I don’t know what his blood type is. He is now 89 years old. Previously I have used Sean Connery as an example as well who is a year older than Shatner, but now, he is in bad shape showing his age.
Shatner doesn’t. He seems to be timeless, both, physically and mentally.
Within my own family, aging processes seem to vary greatly which is why I have always had a strong interest in why people age so differently.
