What do you think are three of those that are, I don't actually want to say the easiest to enact, but I'd rather frame it as say the most reliable. The most potent activators. I think walking is a huge one. Every day I walk. Not only do I try to go on walks just like to be outside and do nothing, usually I take my son for not doing the bike thing, but just some sort of low impact physical exercise, but doing the exercise for the mental benefits, right? Just being outside.
