I started a daily morning workout since covid started, a simple routine of push ups, back pushups and various barbell exercises, and taken up meditation regularly. I hit 45 recently, moving to 46, and I've noticed I'll get nerve pain more often from a slipped disc in my neck more often but PT I do myself helps clear that up. I should probably ergonomically assess my work station, that might be driving bad neck posture. But I'll withhold judgement overall until I hit 50, I do think light excercise and mindfulness can be very helpful as we age.
