Teaser 2909: Pensionable service

From The Sunday Times, 24th June 2018 [link]

A few years ago my father was lucky enough to have been able to retire and take his pension at sixty. I explained to my young son – not yet a teenager – that this was not now usual, and that neither I nor he would be so lucky in the future.

When I am as old as my father is now, I shall be six times my son’s present age. By then, my son will be nine years older than I am now. (These statements all refer to whole years and not fractions of years).

How old am I now?
