A Grandparent's Dilemma...

I've been watching my grandkids grow up... they're always so busy with their gadgets these days. The other day, I found myself looking at some of the games and apps on their devices... wondering if it would be okay to play them too. Am I just nostalgic for when things were simpler? Or is this normal curiosity about what interests my grandkids? Should I ask one of them to show me how these games work... or am I better off sticking to my crossword puzzles and Sudoku? What do you think, should I join the digital world a bit more?...
