I don't believe it's interactivity that's the problem. I've found that if I play a lot of guitar before bedtime, maybe with singing, I sleep very well indeed. Better than I would if I didn't do anything that evening. And making music is interactive, I'm not passively sitting there like if I'm watching TV.
However, if I work on the computer before bedtime it may be that I won't be able to sleep for a while, that typically happens when I'm working on an interesting programming issue and my brain keeps popping up new ideas when I'm actually trying to sleep.

The reason ISPs block TCP/25 is _not_ part of their 'no email service of your own' policy. Blocking of TCP/25 stems from the early days of spamming, when spammers would first relay through, and later hijack consumer PCs for spamming. This was often combined with relaying through a company's mail server, but even when companies got wise to this and changed their setup to not relay, the home PCs could still continue sending spam. Blocking outgoing port 25 put a stop to this (and many companies also block their outgoing port 25, except for their mail server, simply because if an internal computer got infected they don't want to get a spew of spam coming from their network. Just like how the ISPs are thinking). Port 587 requires authentication and in practice only allows you to connect to mail servers you're known to, and there's no reason to block this so the ISPs don't.

As another poster mentioned below: If you show that you know what you're doing, i.e. that there's little risk your computer will be one of the infected spam-forwarding PCs, you can often get your ISP to remove the TCP/25 block.

I fly all the time in my job. Look around in an airplane the next time you fly. Notice what people are doing? They close the window shutters as soon as they're airborne, at least when there are clouds. The reason? You fly above the clouds, and the light from the white clouds gets intense. If the sun is on your side of the aircraft it gets even worse.

A transparent fuselage would be a nightmare, except for night-time flying. But how often do you do fly at night, except for intercontinental flights?

To me the whole sounds like a joke, which it probably is.

Forty two.
