What’s with the huge email attachments???

I mean … come on …

I’m in a cab to the airport and I’m downloading my emails … laptop hooked up to my mobile phone … at 145 Kbps … and it turns out that a business colleague sent me a 5 MB attachment …
Jeeez … I finally download the attachment and excitedly opened it and … guess what? … it was not worthy of being 5MB. It was not even worthy of being an attachment at all. It was a really bad marketing brochure.

Which led me to the latest Summation Law:
The value of an email attachment is inversely proportional to its size.
