I can kinda relate. Some of my whiskers are now pure white, 2-3x normal and tough! However, I do not have a problem shaving them with my Str8 razors.

I think that as we get older ( age 61 here) we will get more & more of the tough buzzard whiskers ( I have anyway)! If yours are posing a significant problem then I would allow your wife to help with the tweezers.
No sense damaging a perfectly good edge!
