Group exercise 'boosts happiness'

They may feel happier than if they were on their own
Exercising together appears to increase the level of the feel-good endorphin hormones naturally released during physical exertion, a study suggests.
Carole Seheult, a sport and exercise psychologist from the British Psychological Society, said the findings were entirely credible.
"Rowing is a sport which requires real team work and endorphins could well foster that process.
"But more generally we know from experience that exercising in groups is good for people at many levels, it's motivational, it's social. Groups sessions really do work."

Should I Drink Coffee?

Saying coffee is bad is a hard sell. It's made mostly of water an beans. The caffeine and oral hygene may be of issue but benefits are well defined also.

I would be more concerened of what is added to the coffee. You may try to alternate every cup with a cup of water.

Many sports drinks add caffeine to boost energy. Also it's a top weight loss supplement.
