Planning for the future can be tough. This difficulty is evident even in your brain too, which perceives your future self in the same way it perceives a complete stranger. When you think about yourself, parts of your medial prefrontal cortex light up. When you think about a stranger, these areas in your brain dim. And they stay dim when you think about yourself in the future. Because your brain struggles to connect with who you will be in twenty or thirty years, planning a life for that person is a challenge. And with the life expectancies of humans continuously increasing, planning for the future may be more critical today than ever.
