I agree, I'd rather the professionals said, 'we're not really sure'. I've come to the conclusion that you and your level of hygiene has to be the thing you focus on.
I am advised by the powers that be not to go out at all. However, my condition means I need to move for longer than 5 minutes up and down the stairs and around the house and doing TV workouts are too hard for me. I need to get my joints moving for at least half an hour and walking is the only thing I can do comfortably.
I am therefore going for a long walk, most days, but I do not touch a thing or get within even 5 metres, let alone 2 metres of anyone. I can open my front door, without touching anything and in any case, no one has touched the handle on my door! I wash my hands regardless, as soon as I come in and to be honest, because I've just been for a long power walk, I get straight in the shower!
DD has been sitting in my garden. She doesn't touch anything I touch, she brings her own drink and doesn't sit near me. Another couple of friends also stopped by for a drink yesterday. They brought their own, sat in the garden and left before they were desperate for the loo, putting their rubbish in the wheelie bin as they left.
I do not believe I am putting myself at risk by doing this, but I do believe that my mental health is better, for having some real life company!
As an aside, how many times over the last 20 years or so, can you count where the weather has been bloody glorious for both Easter and May Holidays!! Bloody typical!
