There is no age limit - only physically capable.
People vary enormously, some people at 90 will be more physically
capable than others at 30.

There may be regulatory limits of course - but in the russian case,
waving sufficient cash around, as long as you can convince their doctors
that you can take it, shouldn't be a problem.

John Glenn was 77 for his Shuttle flight.

Depending on the launch/reentry method, the only
upper limit is probably determined by the health of
the person.  A healthy 90-ish person could probably
safely fly in a Shuttle-like vehicle where a maximum
of 3Gs would be encountered.

There is no "age limit".
Physical and mental health is the determinant.

And of course the ability and willingness to learn safety
procedures and to follow instructions.

Yes.

It's not an age issue.  It is a medical issue.  Use Google.

There is no absolute age limit for astronauts. For example, John Glenn
was 77 when he did his shuttle flight:

However, he got some political support for his approval too.

ESA has preferred age limit of 27-37 for astronauts, when they are
accepted to training.
