I have a girlfriend who hails from Slovacia. She's smart funny and an amazing support. She told me the other day she was using an app to help her mental agility, and was disheartened by her performance. I said I'd use the same app so I can offer her support and guidance. ( to the best of my ability )
I started over a week ago. I find the exercises fun, progressively harder and make me think. It takes just 15 - 20 minutes each day. I thought I'd share this as I have taken some comfort from the fact that I'm doing OK.
