Megastar Amitabh Bachchan misses the unrestrained and carefree days of youth when he used to go for frequent 'chaat' sessions and for drives with friends after bunking college without worrying about anything.

"The excursions with mother to the Bengali Market for the most delicious 'chaat' in the world and the sweet meats. The 'parathe wali gali' in Chandni Chowk, the mad drives during college hours with our gang of class bunkers to the excavations and the ruins beyond Qutub Minar and Tughlakabad, " the 69-year-old, who did his graduation from Delhi University's Kirorimal College, posted.

"The winter sun in the afternoon, the fire place by the night, ghost stories over new year and just the coming together of family and friends wrapped around in warm blankets by the burning embers!"

The actor feels such adventure "is gone now".

"Such adventure, such simplicity, such trust ... all gone now. We slept at night with our doors and windows open, the gates never shut, even when we were out in the lawn or on the roof top, for those were the regions that were the coolest. No security no guards, just a carefree life ...., " Big B wrote on his blog.

"And now just before I have come up to write to you, each door checked and double checked, each window closed, locks and security personnel alerted, Shanouk (his pet dog) in vantage post, phones and alarms by the side, incessant noise on the streets of traffic and people."
