As the nation's average life expectancy is approaching 90, senior life can be divided into two periods. People in in the first period, aged up to 75, can be called the "young old", while those in the second period, aged 75 and above, are the "old old".
For some time to come, baby boomers are the "young old". It would be a terrible waste not to make the most of their vitality.
Many baby boomers are keen to work well into their senior years. According to a recent survey, almost 50 percent said they would like to keep working until age 65, 15 percent replied "until 70" and 10 percent said "over 70".
If baby boomers all retire once they reach their 60th birthday, handing their experiences and skills on to the next generation will become very difficult. This will be a massive loss for the economy.
The introduction of the law for the stabilization of employment of the aged obligated companies to raise the retirement age for their employees in a phased manner. Consequently, companies should implement this measure steadily.
Baby boomers will be expected to play a leading role in changing society into one where people with the will and ability can keep working, regardless of their age.
