How long would it take from warehouse to my house <| sep |> They do more with less . The older you get as a fighter , it seems , the more tricks you learn , how to keep yourself from getting tired , how to tire out your opponent , how to limit their offence whilst giving yourself better opportunities , knowing how to move to keep your opponent from getting balanced and set , etc . Being able to get your opponent to commit whether it be punching or defending without actually doing anything yourself is so effective , and suits aging fighters well . So much of it is cerebral , the ability to think in the middle of a fight is something that does not wear out like athleticism due to the passage of time . As stated by others , fundamentals are key . The simple things like keeping your body and feet angled , keeping your rear hand holding the phone to nullify the threat of hooks , they work because they ' ve survived for decades , passed on from boxer to boxer . You don ' t need athleticism to successfully use them . Just a thorough understanding of the effectiveness and limitations of the human form .
