I was due to retire and so would have time on my hands. I treated myself to a lifetime subscription after trying the games for free. I'm 67 and have reached the top (92%) of my age group. I'm aware that my scores are likely to gradually decrease as I age but I will be happy as long as I remain over the 50 percentile for my age group. It also encourages me to keep up my keyboard skills. My grandchildren play Lumosity and it's fun and interesting to compare our scores in the different categories. Don't take it too hard if you get a low score - you can always try to improve next time.
