Can’t open tins, bottles etc

I find bottle tops on bottles of water notoriously tricky, they seem to be welded on these days, and I have hurt my hand before now trying to turn the tops.
Using a tea towel helps sometimes. I think it got harder when it was decided that bottle tops should stay attached to the bottle after you have opened it.

We have a battery operated tin opener. It's easy to use once you get the knack and get it in the right position.

I can't post a picture of a similar one but they are widely available, online too.

I agree that bottles tops have become harder to open. The worst thing is when, dying of thirst, you buy a drink from a petrol station or a vending machine, yet you can't get the darn cap off. I've resorted to using my teeth before now!
Is it our strength or our dexterity that weakens with time?

I bought a jar of jam from Aldi and couldn’t open it.
Took it back to the shop and an assistant bashed the lid part of the jar on the floor to break the airlock, then unscrewed it for me.
I have now bought a ‘gadget’.

Sometimes you need to break the air lock or run whatever it is under warm water

I think a lot of tins and bottles are more difficult to open anyway. I bought a jar opener that was recommended on here and it’s really helped. You can, I believe, ask supermarkets to open jars for you but that makes transporting them home a bit dodgy, but it means that there’s a demand for it. I’ve had several jars in my larder that I kept for years as I couldn’t open them but didn’t know what to do with them.
