1. Golf Lessons
    If they’re still in search of a hobby or physical activity to do on the weekend (since running can get tough on older joints), consider gifting them some golf lessons. Too stereotypical for you? Sign yourself and your friend up for a Hot Yoga or Mountain Biking class instead of staying on the green. Either way, the gift of wellness—in the form of physical activity—is an among the best 50th birthday gift ideas out there.
