For anyone who was interested in the piece I wrote a few weeks ago querying the timetable for potential therapies that might radically extend human lifespan, Dr Aubrey de Grey has left a reply :
"This is Dr. de Grey. Thanks to you both. All I would offer in my defence is that I do in fact insert "subject to funding" into my replies to questions on timeframes much more often than is apparent, but journalists just leave it out (rather as they insist on describing my goals as "immortality" and so on). My view is that progress in the past seven years or so since I started making these timeframe predictions probably amounts to about two years of the progress I think we would have made with full funding, so it's not as bad as all that."
