Or when playing outside or going for a walk. No phone in pocket means it is harder to get distracted.
It’s much less usable and I hate constant notifications on my wrist, so I’ll usually have it on mute and do a quick check at my notifications occasionally to see if there’s anything urgent (usually work or a message from my wife).
I’ll mostly ignore my group chats on WhatsApp and emails, and there’s no risk of me getting sucked into group coversations with friends, YouTube or the Internet (I don’t have social media apps on my phone so that’s not too much of an issue), which is where the real time sink is for me.
Same thing when going to sleep, I don’t take phone near the bed, just have the watch on which has my alarms to wake me up with vibrate function.
