Weighed down by this entire matter
I reckon he was carrying around all that 'Virgin flair' in his bag, along with a home packed lunch, personally signed copy of 'Losing My Virginity' and some face painting kits, hence the excessive bag weight.
The bag was still a few kilos lighter than one would expect because he wasnt carrying around the Virgin 'must haves'!!
Personally I hope his litigation goes well, I mean the Virgin founders managed to extract millions out of the company for their own future enjoyment so why not this bloke? Go for broke son, claim some PTS also if you can !
