Resolution criteria (provisional):

If 5 or more users post credible evidence of themselves not sitting while doing work this question resolves YES.

It's not necessary for the non-sitting method of working to be the user's only way of doing work, but it must be the case that it could be so without causing discomfort or physical exhaustion. By "sitting" I include any recumbent or horizontal posture.

Further restrictions and requirements:

1. The work has to be paid work or somehow profitable, not just a hobby.

2. The work has to be something that is done traditionally indoors while seated. Programming is the definitive example.

3. The user must provide credible evidence that they've been doing their non-sitting method of working for longer than 1 month. Credible evidence is being able to convince me you're actually doing it (I won't be betting in this market).

4. The user must be able to maintain their non-sitting method of work without needing to take breaks from excessive discomfort or physical exhaustion. They may take some breaks from their non-sitting posture to e.g. sit, but only in the same way that one might take a break from sitting to e.g. stand or walk around.

There's also restrictions on the users who are eligible:

1. If you are posting under your real name, you are automatically eligible.

2. If you are pseudo-anonymous (like my account) the account cannot be an alt account. Be prepared to undergo procedures to demonstrate the non-altness of your account. This may include you making a market like /singer/am-i-an-alt-account
