For a low tech fitness solution, google "Office chair workouts". You'll see lots of useful stuff like this . It is mainly about resistance training (non-aerobic workout), so if you want to go full in on resistance training, you could just get some weights and even one of those hand grip devices and start pumping iron while you crunch numbers on the computer. But fitness aside, if you want a healthy career then you should be proactive with your time and do things that you are not asked to do.

Astronomy and mathematics are two of the remaining professional academic disciplines that are still open to significant contributions from amateurs, hobbyists, and other unaffiliated individuals. This is likely to do with the nature of research in those fields, such as the fact that almost everyone has access to the sky, or the ability to experiment with abstract mathematical ideas. It is not just about things professionals have not 'bothered to check', but rather there is still so much to learn out there in astronomy and mathematics that people from a wide variety vocations can "stumble" across new discoveries. See this list of amateur mathematicians and their original/primary vocations. You have primary school teachers, lawyers, an innkeeper, as well as engineers and scientists from other fields and many many more.

I encourage everyone who has an interest in astronomy and/or mathematics to dabble in those areas with the understanding that they too can still make new discoveries. Try joining your local astronomy club, or an amateur mathematics society , or just keep dabbling and observing, and don't think "I could never make a real discovery," because it is possible.

Why is it that people who have evaded authorities find it irresistible to gloat about how "clever" they are to have outwitted cops. I get it, maybe eventually talk about it in an autobiography, but he may technically still be evading said authorities. He might as well say, "nanna nanna booboo, come and get me!".

Note to self: always carry a roll of aluminum foil in case I am chased by a helicopter at night.
Then I can say I am going to a space convention or something...

Those proposals seem like terrible ideas, but it is no surprise given the countries that proposed them. It is just sad to see what it finally takes for the republicans and democrats to agree on something. Maybe if we tell them that the UN is going to forbid countries from implementing a single-payer health system, then congress will decide to implement it out of spite.
