90% of oldage illnesses happens from brainrot ... lack of oxygen cuz of corrosions of veins and arteries ... and your erythrocytes just crack, explode like a baloon before they reach your brain ... to prevent you need to care about your straight walking, selfmassage on headskin, face and your neck, body core for straight body ,,, and train your legs ... cuz they are the biggest muscle on your body ... and the muscles are your second heart. they continue to pump blood even your heart can stop for awhile. *,.*
