I don't think Aubrey is a cynic at all, with what he is doing for life extension--quite the opposite (about supplements, and CR he is realistic--along the lines of realism he is signed up for cryonics in case it will work, because it is likely, not impossible--but likely that humans will not end aging in his lifetime).
cyn·i·cal (sn-kl)
adj.
1. Believing or showing the belief that people are motivated chiefly by base or selfish concerns; skeptical of the motives of others: a cynical dismissal of the politician's promise to reform the campaign finance system.
2. Selfishly or callously calculating: showed a cynical disregard for the safety of his troops in his efforts to advance his reputation.
3. Negative or pessimistic, as from world-weariness: a cynical view of the average voter's intelligence.
4. Expressing jaded or scornful skepticism or negativity: cynical laughter.
What I meant is that he seems cynical toward interventions we all have access to. He obviously thinks supplements and proper dietary attenuation will have nill effect on our lives. I think he is wrong.
He doesn't say nil, nor even negligible which I think you meant--but for any matter it is more of a, "yeah realistically the amount is small, and you should stay happy and do what you enjoy in life" sort of person-- here is an actual quote of his on CR:
"For the avoidance of doubt: though I think that CR will probably give humans only 2-3 years of extra lifespan at most, I certainly don't disapprove of it -- the health benefits are clear, as shown in the Holloszy and Fontana work, and even 2-3 years may make a big difference to quite a lot of people. So I approve of CR."
From April's Blog:
http://www.mprize.or..._de_grey_1.htmlApril is Michael Rae's girlfriend--both follow CR, very nice people and stimulating to hang out with. (Michael Rae is Aubrey's co-author for Ending Aging and they've had many discussions about the science of CR

)
Also, on the note of this thread--anyone that travels to Cambridge to meet Aubrey, he will most assuredly take them to a pub for a great beer--so you can go ask him yourself and give a report in the thread
