I offer no opinion on what the maximum age should be for international officials.
However, I take offense at the suggestion that officials should stay home and enjoy their grandchildren.
Many people do not have grandchildren (or children) of their own. Some of them may have wanted to, but life didn't work out that way. Others may never have wanted that. For various reasons either way.
At a local level, many clubs rely on judges and other volunteers past retirement age (with or without grandchildren) to get their skaters tested, staff club-hosted competitions, and otherwise keep the clubs running when younger adult skaters and parents of skaters are too busy to volunteer their time. Some who scale back from national or international competition judging to a more local level instead, and some who don't even start judging (and therefore never reach high levels) until after retirement. I've seen a few judges still going strong locally even into their 90s.
Of course it's easier for local clubs to be aware of when it's time to stop inviting specific officials as they age.
Enjoying one’s grandchildren is a figure of speech, I did not mean to imply that every person of a certain age had grandchildren. I think I’ve lived long enough to know that.
I stand by my opinion that the maximum age for officials should not be raised. Although it would not affect me, (assuming I had the knowledge, the connections or anything else that would lead me to be a figure skating official), Spousal Unit is not so far from that age where retirement is currently mandatory.
And I am sorry, there is a time at which retirement for this position should be mandatory, and I will shake my old lady cyber cane at anyone who says different. I am certain that there are many other ways in which they could be involved in the skating community, and they could do that if they so choose.
