I also play chess online and it does take the mind off of age-related worries.We must all learn to accept everything that happens to us such as pain, impairment and, yes, even death. I'm 89 and was already in Vitas Hospice several years ago. Very few leave Vitas Hospice ALIVE! I left after only 3 weeks. My geriatrician has been telling my I have only 1 year to live. He's been telling me that for 5 years already. He told me he will NOT treat me for cancer or heart disease if I contract either of those terminal illnesses.
I'm 89, my neck is bent from arthritis and walking is difficult. I try to walk 1 twenty minute walk every day to avoid a wheel chair. Luckily, my wife is still alive and she has become my care giver.
To keep my mind active I play chess at Chess.com and Civilization VI at Steam.com every day. I lose myself in the games so do not dwell on my age.
