It was at the age of 8.
When my teacher lifted me in front of whole classroom.
Actually , she was explaining the human body and its parts...so for demo she looked for lightest student and i was lucky for being only 17-18 kgs.
She was tall and way stronger , she called me up and asked to stand on table..so that everyone can see me , however soon she realized that i can't because of table height.
She lifted me front

and then started showing my hands , legs eyes etc to whole class. I was embarrassed initially but later started enjoying it
Since then i started enjoying Lift and carry.
