One way is with electricity⚡- but how you use the electricity really matters

This paper is probably the last one I get into the lab and do *most* of the experimental myself. Perhaps why it started in 2021 and it took 4 years to finish. 🤦‍♂️

So your Attention Score went down because people are rage-deleting their Twitter accounts.

Why is that happening? Should I be worried? Should I see my doctor?
