How do you stave off mental decline?I’m almost 30 and starting to feel the affects of mental decline. I’m having memory issues even though my memory has been like excellent in the past. I do puzzles to try and keep my problem solving skills sharp but I don’t feel it has an affect on me. I used to be really really good at math but I’m crapping out.I’m too young for this be happening man! I took a dna test and it’s said I’m at risk for Alzheimer’s! What the hell man.
