50ish here. If I'm ever looking for a new job again [hopefully never!], I'll be sure to dye my hair and drop dates from my job history.
Instead, I include my job history over the last 10-15 years, and include select items that are older than that if they are particularly relevant to the position I'm applying for.
I don't try to hide my age -- my age/experience is a significant advantage I have over most other applicants. Age discrimination is a real thing, of course, but is very far from being a universal issue. If a company doesn't want to hire me because I'm too old, I count that as dodging the bullet of getting hired by a sketchy company.
