Most people I know say they want to lose weight. Likewise, most people say they don't exercise enough. Numbers can be involved with both body weight and exercise. You may have heard of 10,000 steps a day and you may have come across challenges and other studies that 5,000 or 7,500 is a better target. You may have heard or read about body mass index, which has been quoted as being healthy at 25 or so. We have read that older people, say 70 and older, do better with a body mass of 27.

In the matter of weight and exercise and social relations, it can help to review one's feelings. Not your partner's feelings or your parent's or the guru's or the pastor's but your own. When reviewing, it can be helpful to ask what your immediate reaction to a question or subject is and note it down in writing. Then, ask
Where did I get my idea of what I 'should' have (in money, or weight, or friends, or …..) ?
How up-to-date is my idea of what is appropriate for me?
Up-to-date for my current age, health, status, etc.?
Up-to-date in accord with current knowledge?
It often works better to assume a critical attitude toward one's thinking and then follow that up with a supportive stance, one that you would use with a little kid, a different one for a brother or sister about your age, and one you might use with an older, confused person.
We are all living our current lives. Let's aim for a joyful, pleasant, balanced one.
