Sometimes an old athlete may want to come back for some special match. Some bettors might still bet on him despite of old age and lack of recent experiences in the sport. That is because of what we call nostalgia. They might recall the past memories or past performances of the athlete that may not necessarily reflect the recent performance of the athlete. So be careful when betting because you might just be nostalgic.
This is good advice for collectors as well. I’ve recently found myself overpaying for items I’m collecting because of nostalgia. I’m ok with it because you have to do what you have to do to get items that aren’t for sale anymore. Always be aware of what you’re doing. It is ok to overpay or spend money on nostalgia if it makes you happy.
