Take glutamine for joint health. Go and lift free weights. I lifted free weights from 19 to 37. Till a herniated disc and a pinched nerve ended my hobby (overloaded my squat of 120 kg) Looking to get back soon as I got no more pain. Muscle atrophy starts around 30s. Lifting weights slows down this process. Take magnesium supplements for better sleep. I am not sure about your pre existing other health conditions. Do some research and consult your doctor before taking any health supplements long term. I have insomnia and other problems (genetic). Currently, on Magnesium Clycinate. My sleep is good. Previously, on Magnesium Taurate. My only issue is the afternoon slump between 2pm to 4pm.
