As an 80 year-old semi-retiree, whose work really doesn't take more than an hour a day, I would wake up each morning wondering how I was gonna keep myself busy and entertained during the day.
Apart from logging on to terb several times a day, watching old and new TV series, and general internet surfing, my days were rather empty.
Also I was becoming too sedentary.
So I decided to take up "mall walking" about 8 weeks ago. Fortunately there is a large shopping centre close to me, with covered parking, so it's my garage to it's garage no matter what the weather.
I bought a Samsung Galaxy smart watch on Amazon, that counts my steps and can check my heart rate.
I am now up to 8,000 to 10,000 steps a day, 5 or 6 days a week, am enjoying a renewed sense of energy, and am amongst people instead of being home alone.
There's a lot to be said for exercising, especially around other people, as a remedy for emptiness in your life, or other negative issues.
I've even found it's reduced my dependence on hobbying as something to look forward to...
