Just turned 50 yrs. old. Have done some martial arts in the past (15-20 yrs. ago: kung fu; tai chi; aikido). My son is doing judo, and its caught my interest. What do you think? Is it too late for me to give it a try? No goal other than to learn. My plan is to work out for the next few months in order to get in better physical condition before I begin. I've been stretching regularly for the past few years, and intend to add aerobic (goal is to do a brisk 2-3 miles run), plus some strength training. Maybe do some aikido course in order to work on ukemi. The judo sensei is very good, and sensible, and would not push it too hard. All advice welcome.
