I saw an article today where some "expert" was pushing a return to 'prevention measures" because COVID is slightly increasing in some places. If we've learned anything from COVID it's that you can't trust the media annointed experts.
Real COVID-19 prevention is going outside abs exercising in the sunlight abs fresh air to make vitamin D and stimulate the immune system. Also eat plenty of fruits and veggies and drink plenty of water. Get good rest. Everything else is nonsense.
