You are as old as the last time you changed your mind.
- Tim O'Leary

My scientific specialty is chronobiology (circadian rhythms and photoperiodism), with additional interests in comparative physiology, animal behavior and evolution. I am not an MD so I cannot diagnose and treat your sleep problems. As well as writing this blog, I am also the Online Discussion Expert for PLoS. This is a personal blog and opinions within it in no way reflect the policies of PLoS. You can contact me at: Coturnix@gmail.com

YES! Send me a free issue of Seed.
If I like what I see, I'll receive 5 more issues (6 in all) for just $19.95. If I'm not completely satisfied, I'll simply write "cancel" on the invoice and owe nothing. The free issue is mine to keep.

In that case I must be about 3 seconds old most of the day.
