I was about 5 years old, when a girl of 8 years lifted me in cradle style during a holiday. It was an immensly beautiful feeling and I think this triggered everything.
In fact, I am happy that I have (or have discovered) the passion for lift & carry, since it is something powerful enough to pull me away from negative/sad thoughts ever since.
I was only very rarely lifted by girls as a kid (I remeber three situations), but, approximately beginning at the age of 22, a long series of lifts and carries in various situations and settings began lasting until today.
I guess, it is part of my lifestyle.
