Heard on BBC World Service Science Hour, which means you can probably download / listen to interview if you're interested.
Interview with Professor Todd pricked my ears when he was discussing intrinsic human immune system's ability to react, being confirmed as seasonal plus daily. Yes, we've suspected it but this is hard research confirming it.
Something he said made me hope my GP was listening. That is, this research confirms that what time of day we take medications really may make a difference. This is something i find true for me but which my GP categorically denies.
Hope this research might eventually lead to improved treatment for all sorts of autoimmune diseases, including us Hashis folks.
