After spending 1 hour reading just the content of the content of this book, we have experienced but aged and grown 1 hour older than before.
Even the kids in the picture still look young, but they are at least 1 year old if they can run like this. Aging of the Brain is really not so scary if we put it in a different perspective. So, a 100 years old person do have something to celebrate and look forward to, on a 150th birthday.
