laughter preserve your youth

some friends i know, think i laugh to much (sometimes)
and laugh too easily for those not-so-funny jokes

and yeah, i like jokes and funny and interesting stuffs
and i like it when i am happy

but in contrast, i always prefer to come out with "lame jokes"
which tries to make people laugh solely because of the lameness of the joke

somehow, most people i know doesn't really into "lame jokes"
hmmmmm,is it something to do with my sense of humour?

which reminds me about my friend keep on saying that i look young
for a 21 year old guy like me they think i am still 18-19 years old =________=
for reference, i am 168cm tall and weighted 52-55kg (60kg++ during and after Chinese New Year)
kinda a thin guy, in my opinion

for those who thinks i look younger than i should be
i shall answer them: "i sleep on ice"
