Last Sat at food market, I chatted with 4 seniors in the late 60s to early 70s. From their mannerism n speaking, one can tell that they are well educated and held important roles before their retirement. Two were seen with walking stick, with one suffering from Parkinson. From web search, I noted that one was a ex-Director in a MNC. My takeaway : 1. 70-yo age tier may reveal our chance of longevity, mobility & mental health state. 2. We still have 10-years to work on it. 3. Do we mind having online public traces of ourselves ? We took a group photo. One of them requested me not to post onto online media.
