Thanks guys!
Reason I was wondering is cos my luggage felt really heavy when I went on holiday and I remember that it was weighed at the airport and was 20 kilos and I was thinking I wonder if Ive lost that much....
Just worked out that what i've lost since May equates to how heavy my luggage was, plus the weight of my partner's luggage (38 kilos in total)
(I could barely drag my case, never mind lift it...no wonder I was so nackered walking up and down to the beaches last year, Im just imagining carrying both cases round with me, cos in effect thats what I was doing!!!!)
