I'm 58 and my wife is two years younger. We do a few short hike each month, maybe up to 6km about 3 hours (often with our dog). We also do longer ones 3 or 4 times a year, maybe 10 to 15km, 300m ascent in about 6 hours. We just enjoy the scenery and identify plants, enjoy rock formations and the occasional run into fauna. Just take your time and maybe a friend to keep you motivated. The physical side of things does improve as you learn about muscles you didn't know you had. Before we started doing it more regularly, I complained a bit about my knees and ankles - not so much now. Also get appropriate footwear - we've been pretty happy with what Merrell and Keen have on offer (and also Teva Sandles for summer walks)
