Despite everything, Telegram is actually great. It’s only bloated if you’re using the features on the device, the client is opensource and native apps for any platforms, it’s very lightweight compared to other messangers and even to some dedicated solutions, it sends stuff p2p on the same network so you don’t need to care about the traffic, but also it allows for on-demand downloads so if you want the stuff will be available outside of your network.
Alternatively, kdeconnect, but I find myself using Telegram instead 9 times out of 10, even though I have both installed.

Or alternatively it’s a win of messaging, it’s so easy and convenient it can be easily used for the purposes not intended

I bike and rock climb, I walk long walks and overall in a good shape, not great, not terrible. When the doctors see my bmi without other metrics, they immediately tell me to lose weight and don’t take anything else seriously. I missed very serious illness because of that, every symptom I had was thrown into a pile of “your bmi is bad, lose weight”, until one doctor was smart enough to check on me for real.
BMI is incredibly oversimplified and gives lazy or overworked doctors easy way out of doing their jobs, which kills people.
