Problem Statement

My friend, Henri, tends to sit in front of his computer for long hours at work. Even though he knows the importance of taking regular breaks to stretch and distress, he often forgets to do so without proper reminders. On the occasions when he wants to take a break, he'd love to mingle with his colleagues. However, the current flow of having the intention, opening up the slack channel, thinking about what to say, typing up the message, then clicking on the "send" button sometimes have deterred him from actually taking a break with others. How can we nudge Henri to take and enjoy the breaks?
