Throw out all your ideas about what time is..this book will clear up plenty of misconceptions.

A couple of interesting things I learned by reading Hammond's book..1) that there is no organ in our body that keeps time. 2) That there is a species of Hummingbird that can accurately time a flowers replenishment of nectar/ which is every 20 minutes. Amazing.
Loved the chapter about why time speeds up as we get older. i.e.: While a week with nothing planned stretches ahead of you if you are eleven and it is summer vacation...as an adult, in the hopes of redecorating your house and before you are even halfway through, the week has rushed past.
Time has an impact on memory, memory shapes our experience of time. To make sense of our memories we rely on time to link us to events , and develop a timeline. What intrigues Hammond about the sensation of time speeding up is that it is something we often discuss, but to which we never seem to become accustomed.
If you are looking for something just plain interesting to read, this is the book!
