As we get old, we feel little sad about losing vigor of youth and energy of life. Few weeks back, I was in Atlanta zoo with my kids. I learned Flamingo borns gray as a baby. Flamingo gets pinkier, prettier and more desirable as he or she gets old. On that day, I learned that pink color comes from deposition of molecule called canthaxanthin which accumulates via their diet. Zoo-keeper made an interesting comment: "Those of you who are getting old should feel happy as getting old makes you more beautiful". At least, I find some solace!
* I am not a big fan of Zoos for various reasons but Atlanta Zoo is one heck of a place to visit.
