can you imagine, how many times he got his neck cracked by one so called barber/massagist/therapist... without the proper technique, force or care? miracle is he can still walk with a decade of that kind of massages xD
unfortunately massage and chiropractor work is shown to not actually help long term issues. Most it offers is temporary relieve, and many doctors are just so bad they cause permanent issues to patients
Rumen told him he needs to excercise. Chiro only offfers temporary relief. For serious problems, like scoliosis, kyphosis and others, long terms excercises, good diet and overall balanced life are better. And barbers shouldn't be cracking joints, wrong handling can lead to severe and permanent damage.
