A little hard of hearing!

A 92 year-old man went to the Doctor to get a physical. A few days later the Dr. saw the man walking down the street with a gorgeous young lady on his arm.

A couple of days later the Dr. talked to the man and said, "You're really doing great, aren't you?"

The man replied, "Just doing what you said Doctor, 'Get a hot mamma and be cheerful."

The Doctor said, "I didn't say that. I said you got a heart murmur. Be careful."

Catalysis

In 1823, the effect of platinum as a catalyst was investigated by Johann Wolfgang Döbereiner, who found that hydrogen combined with air in the presence of platinum powder to form water, in a reacttion so vigorous that the filter paper holding the powder was charred. (It was later that the term catalysis was coined by Berzelius, in 1835.) Within a few days, on 3 Aug 1823, he invented the Döbereiner lighter process using the effect he had observed. He ignited a thin jet of hydrogen by passing it over spongy platinum in air. He designed a jar-type lighter using this method. Within three months, news of his discovery had been reported in some dozen European science journals. His lighter design was taken up by manufacturers to replace starting a fire with flint and tinder, and was in production for several decades.«
