Yes of course. I guess my point really is that it should have an impact on numbers soon, not cos of the threshold, more cos of the kind of person who it can reach. I think its fair to say that a big majority of the ones getting it right now are simply more likely to get by the very nature of how they live and what they do. Those who work in public facing jobs etc, or those being a bit less cautious with the rules/hygiene.
Eventually those people will have been hit, the easy tinder to light so to speak, and there will be less of that easy tinder available for the virus. You can only presume that rest who haven't had it are either lucky, which will be a lot admittedly, or most likely (the majority of this bunch i'd guess) just relatively hard to reach for the virus given lots are working from home, washing hands and sticking to the rules pretty much down to a tee. I'd wager that's still a pretty big chunk of the country.
So in theory it should hopefully slow down if its burning through those currently more susceptible (through lifestyle) given that getting it to the next bunch of people isn't as easy as they're a bit more hidden away. I think we forget that it can't necessarily reach everyone at the same speed because some are just more much statistically less likely to get it. Home workers etc. The first 25% will be the ones more likely to get it, the next 20% should be a bit harder, and the final chunk even harder after that. Each time the spread should thin out in theory... Hopefully if this is the case it should slow down and buy us some time for vaccines.
