I'm nearer 70 than 60 and for the past 2 years have only been able to hobble a few excruciatingly painful steps at a time leaning heavily on two sticks.
Last time I went to the corner shop (before the first lockdown) I had to abandon my shopping trolley and leave, because the queue for the check out was so long I realised if I stood waiting I was going to collapse before reaching the till, and certainly wouldn't be able to walk the 150 yards home afterwards.
I used to have a capacious shopping trolley that could handle a big shop of heavy items, it was the kind with two wheels that you pull along behind you. Impossible to do once you reach the stage of needing to lean on a couple of sticks.
I started wondering if there were trolleys that you push in front of you, that were stable enough not to tip over if leant on, and discovered that they existed and some of them were designed to also be used as seats (solving the problem of long queues for the checkout).
Since my legs are too feeble to lift me without assistance from my arms I paid a bit more to get the version with armrests. https://www.walkandrest.com/armrest-shopper/28-58-the-new-armrest-shopper-red.html
When it arrived (already assembled in the huge box) the first thing I did after unfolding it and working out how to set the brake was to tentatively lower myself onto the seat, to my relief it was just the right height from the ground, very comfortable, and stayed steady when I hoisted myself upright pushing on the armrests.
It also turned out to be much easier and smoother to walk with compared to shuffling along with a couple of sticks. I'm still very slow but can lean all my weight on the handle, shoving the trolley along in front of me, and concentrate on using my legs properly. It's not just a combined shopping trolley, zimmer frame and mobile personalised park bench, it's a rehabilitation aid!
After a couple of years of not being able to walk to the postbox (25m from my front door), I now have the confidence to venture a little bit further every day. My leg muscles are very weak and atrophied, but when I get tired I can safely stop anywhere and just plonk myself down for a rest. The older and more doddery I've got, the more I notice how few and far between the outdoor seating options are. When the weather gets warmer I'm going to pack a thermos and biccies into the trolley basket and park up somewhere sunny for a tea break.
I love it and wish I'd discovered it last year.
