I haven't researched it,
but it's just my guess,
I think he's still receiving a disability pension,
but what do you think?
But as you can see, he's working, and he can work.
Even in the past, people thought they couldn't work,
but with technological advances,
it's now possible to work.
But I think many people who receive disability pensions
keep quiet even when they're able to work,
and protect their vested rights.
However, the opposite is also true.
People who think they should be able to work, but are unable to.
Even if the situation has changed since the disability pension was first established,
there are probably some people who want to continue receiving their pension.
It's not just the welfare system,
there are standards that need to be changed from the past to now,
but whether they're just following the previous year's system or there's vested interests involved, they haven't changed,
and no one is trying to change them.
For example, NHK has benefited greatly from the old system,
but teachers have suffered disadvantages.
